Have you found the missing Beijing middle school teacher Ren Tiesheng?

1.30 What did Teacher Ren do in the afternoon? Why didn't Mr. Ren get closer to the hawthorn platform two or three hundred meters away? Why not choose to camp on the arbor hawthorn platform?

Teacher Ren 1 1: 00 or so went up the mountain and walked along the road. Under normal circumstances, he should be able to reach the summit at 12: 00. It is basically certain that before approaching the main peak, Mr. Ren basically walked along the path, and the speed should not be too slow. It is possible to stop constantly to observe the terrain and memorize the road signs. It takes at most half an hour. Even if you get lost on the hillside of the main peak, you have to walk through the bushes for half an hour at most. In this way, Mr. Ren should reach the summit around 13: 00 at the latest. Camp A of Teacher Ren's No.30 is about 600 meters south of the main peak, and the dark time should be around 6: 30. No matter how careful a teacher is, he should not start looking for a camp before 17: 30. So, what did Teacher Ren do in at least four and a half hours? Did you go around Tito Mountain? This seems unlikely. If we don't misread the road signs in the newspaper, we can clearly see the top of Tito Mountain (more than 500 meters away) from where we got lost when going up the mountain. This shows that the visibility is not bad at noon on the 30th. If you return to the original road immediately after reaching the summit, you should not get lost only by relying on the general sense of location.

Speculation: Teacher Ren didn't try to return to the crossroads immediately. He chose another mountain route and failed to get through. In the evening, he reluctantly returned to the foot of Tito Mountain and had to camp on the spot. This also explains why Mr. Ren didn't go near the Hawthorn Terrace two or three hundred meters away, and why he didn't choose to camp on the Hawthorn Terrace.

There may be several reasons for choosing another road to get out of the mountain: First, the traffic at the crossroads is inconvenient, and it is far away from Wang Ping Station at the foot of the mountain (more than 10km), and it is not easy to rent a car in a small village. Second, I don't want to go back. Third, it's still early. You can go out from Dishuiyan in the southwest, from the route of Xinhanbiao-Huang Yu Temple-Lime Soil in the north, and from Tanzhe Temple in the southeast.

Where did Teacher Ren go on the afternoon of the 30th?

First, if you choose Tanzhe Temple, it won't be too difficult to go to the crossroads first. If you can't get through, you have to choose to go back to the crossroads. There's no reason to go camping in Tito Mountain.

Secondly, if I choose Dishuiyan, I have never traveled in this direction, so I can't judge how likely I am to get lost or meet a cliff. However, if it doesn't work, it should be reasonable to go back to Tito Mountain the next day and camp at the crossroads. Moreover, there is probably no long-distance cell phone signal in this direction, which explains why Ren didn't call home after determining that he couldn't go home that night.

Third, if you choose the northern line to go out of the mountain, from the map, the ridge extending northwest from the west side of the main peak to Dahua Coal Mine and Huangyusi is relatively flat, which is the most likely choice. I wonder if any mountain friends have searched this ridge? Can you pass? In addition, because it is closest to Dahua Coal Mine, is there a so-called danger zone of "shaft" in this mountainous area? Considering that there is probably no detailed map, it is also a possible choice to stand on the main peak and only rely on your own sense of orientation, direction and visual effects to choose true north. I didn't cross the ridge north or northeast of Tito Peak. However, judging from the big ditch on the outer edge of these areas, there is a great possibility of encountering cliffs in this area. And because it is difficult to pass in this direction, there is unlikely to be a path, so if you go in this direction, the speed must be very slow and hard. If it doesn't work, it is reasonable to go back to the camp at the foot of Tito Mountain. Of course, from the topographical point of view, on the ridge north of Tito Mountain, most mobile phones will have signals, and people from that area to Camp A will pass through the top of Tito Mountain. Under normal circumstances, there is a signal at the top of Tito Mountain, although it is not ideal. Of course, it is not excluded that the fog after evening will affect the communication distance.

2. Why did Teacher Ren leave the campsite at noon 1?

Analysis:

Teacher Ren is a geography teacher and has rich experience in climbing mountains. In general, there is no possibility of losing his direction. Although Mr. Ren may not have been here, you must pay great attention to landmarks and road directions when asking for directions up the mountain. In general, there is no reason why he can't find the direction of retreat. When Mr. Ren goes up the mountain, he will also pass by the gazebo. Mr. Ren is not familiar with this place, so it is impossible not to notice this tree, the platform below and the hawthorn tree next to it during the climbing process. If Mr. Ren 1 reaches the trees on the platform of Hawthorn Forest and continues to move to the northeast, even if no path is found, it is not too dangerous to walk along the ridge, and the possibility of an accident is very small.

Speculation: Mr. Ren didn't bring directional equipment, and the visibility on the mountain must be very poor on June 5438+1 October1Sunday, and there is probably fog (see the appendix at the end of the article for supporting materials on weather). The iron frame, trees, platforms and hawthorn trees on the top of Tito Mountain, which could have been seen in a glance on a slightly higher hillside, are now out of sight. Therefore, Mr. Ren can't choose the best route through the hawthorn platform by landmarks. It is also difficult to determine an accurate direction to explore the road. This also explains why he delayed leaving the camp until noon the next day: Mr. Ren hoped to use the sun to determine the direction, and delayed until noon, indicating that the fog was very heavy. When we left the camp at noon, the position of the sun was probably not clear, but considering that the period of the strongest sunshine had passed, it would be dark in six and a half hours (considering the fog, there might be only five and a half hours left), Teacher Ren had to set off in an unknown direction. When he set out, he judged the direction, which may be based on the sense of orientation of some markers near the camp the day before, or it may be based on the faint light contrast in the sky. Anyway, it's probably not very reliable. Moreover, even if the sense of orientation of some markers near the camp is judged correctly, once you leave the camp and detour in the bushes, you will soon lose your correct direction.

3. Teacher Ren 1 Where did you go after leaving the camp?

Teacher Ren's subjective intention has been clearly stated, "move northeast along the ridge to Shidao Village". So, how did he understand this sentence?

A. move northeast along hawthorn camp.

If Mr. Ren 1 can accurately judge the direction of the camp and his position relative to the main peak, then he should move northeast from the camp (which is actually the best choice) and soon reach the trees on the platform of Hawthorn Forest. Even if he hasn't walked here on the first day, it should be easy to find a way back to the crossroads around here. Therefore, from the platform of hawthorn forest to the northeast until the crossroads is the most likely direction for Teacher Ren to choose. Even if you can't find the path, it is relatively simple to travel along the ridge from the platform. The first signpost that has been in office has no Dazhiling, and the ridge can always pass without a cliff. At the first signpost, signposts in all directions are obvious, so there is no possibility of getting lost. However, the section from the intersection to the Hawthorn Terrace has been searched many times, and it is unlikely that there will be dead ends. The only possible dead angle is the hill just east of Tito Mountain, which is about half the distance from Tito Mountain to the crossroads (hereinafter referred to as "Tito Shandong Highland"). This highland has been searched many times, but I wonder if the ridge north of the highland has been searched? If the ridge in the north meets a cliff, then the ditches on both sides of this ridge should also be found. Xifanggou,1/No.6 group, 18 group (15 group? ) It has been searched carefully. I wonder if the ditch in the east has been searched?

B. move along the ridge extending northeast of the main peak.

As mentioned above, Mr. Ren is probably not sure about the direction. He should be very clear that it is easy to lose his current direction in the fog. Therefore, he may choose to return to the crossroads from Tito Mountain along the northeast ridge for the following reasons.

First, when the fog is disoriented, it is not easy to get lost along a ridge with a clear direction.

Second, Ren Qing's crossing is in the north of the mountain, and the straight-line distance is less than 3 kilometers;

Third, Ren 30 may have seen a ridge extending from the top of the mountain to the northeast.

Fourthly, without detailed contour map, it is impossible to foresee that the ridge will be cut off by cliffs and ditches.

Fifth, when Ren goes up the mountain, he may notice the ridge in the north of the path, and the ridge in the north of Shandong may make Ren guess that the two will meet somewhere.

This also explains why Ren used the word "ridge". After all, the route A from the camp directly to the hawthorn platform is closer to the crosscut than the ridge.

If so, Ren Zhengfei is likely to get into trouble. In addition, many ridges branching eastward and northward from Tito's main peak are cliff structures, so it is likely that Teacher Ren will consume a lot in the process of constantly trying these ridges. After hitting the wall many times, it is getting late, and Mr. Ren is likely to risk jumping off a cliff or ditch from a relatively gentle hillside. Because, Mr. Ren may feel that his water, food and physical strength do not allow him to stay in the mountains for another night. If so, Mr. Ren is likely to be trapped between two cliffs or injured on a cliff somewhere.

C. because the direction is completely wrong, I choose to move to the southeast ridge. This ridge is very short. If you don't change your direction, you will soon go down the ditch, and it is unlikely that the Zen room will receive its shutdown signal at 4 pm. So, it is unlikely.

D. Because the direction is completely wrong, I choose to go south along the ridge (the direction of the wine cellar). There should be hope to communicate with the meditation room before reaching the high point of wine leakage. But from the picture, the journey from the camp to the wine cellar should not exceed one hour. Four hours after the departure, it is unlikely that Ren will still wander on the north slope of Jiulongzi.

Three. reason

To sum up, I personally think that the area where any teacher is trapped is most likely to be concentrated (the possibility is decreasing).

1. The ridge areas in the east and north of Tito Mountain and the valleys and cliffs between them;

2. The ridge in the north and the ravine in the east of Tito Shandong Highland;

3. Near the main peak of Zigou on the ninth floor.

It is suggested to consider paying attention to the above areas again. I think Mr. Ren is probably still near Tito. Think about the search and rescue in the Niangniang mansion, and you will know that our search often leaves many dead ends. Besides, it's useless to search for more people on the terrain. It is suggested that the commander choose the mountain friends he knows and trusts to form a three-person team and search according to the specified scope.

Appendix 1 Weather information near Tito at the time of the incident.

Most of the mountain friends who exchanged views thought that the weather was fine on 9.30- 10. 1. I also believe that the weather is good on the 30th. However, logically speaking, teacher 1 is probably at a loss. It is one way to check the weather records of Mentougou, but Mentougou is far from Tito Mountain, which may be very different from the climate in mountainous areas. To this end, I would like to refer to the Tanzhe Temple in the southeast. Because Tanzhe Temple is the nearest important landmark (about 8km), and the two places are in the same mountain area. During the Eleventh Period, there were many tourists, leaving many travel notes and photos on the Internet, which can accurately reflect the weather conditions of Tanzhe Temple in that year.

I don't think I have found it yet
