Starting from Changchun, I will go to Ji 'an first, and then go to triangle longwan for two or three days. Seek strategy, ride and accommodation plan.

You're beating around the bush. You can go to triangle longwan first. Personally, I think there is nothing to play in triangle longwan. What happened? You can go to Ji 'an to play. Look, Tonghua has buses that know about Jiaohe, but Ji 'an doesn't. There is only a bus to Yanji in Ji 'an. Ji 'an is close to Chaoyang Town, and there is no direct bus. There are direct buses to Meihekou and Liuhe in Ji 'an, which are available all day. Before 17, there were 10 flights to Tonghua from morning till night. There is nothing to play in Chaoyang Town, a poverty-stricken county in the province, and there are no special tourist attractions. Traveling in the northeast border is completely enough. What else is there to go to Chaoyang town? There are two buses from Changchun Expressway Bus Terminal to Ji 'an, one at 7: 30 in the morning and the other at night 17. Ticket price 100+, the bus is too slow and the sun is too bright during the day. When you go to Ji 'an at night, you can choose to stay in a general inn, and the environment is not bad. Standard room 80, smaller 40, Holiday Inn 260, deposit 500- 4 stars, five-star Ziduyuan. In Binjiang Government Square, the environment is good, and the software and hardware facilities are good. After the standard room is discounted, the deposit is 398. I don't know if you are a photographer. Or is it just a shock? In the morning, you can choose China-DPRK Friendship Bridge or Qingshi Yunfeng Dam as the first stop. There is a bus to Qingshi Town in Ji 'an, and the fare is 7 yuan, 50 kilometers. When you arrive, you can see North Korea at close range, very close, and you can also see Korean female soldiers. You can take pictures from a distance, but not from a close distance. You can also talk to North Korean workers, but you can't take pictures. You can throw things at them, and so can cigarettes. When you come back, you can choose to eat some special barbecue in Ji 'an, Jindalai, and some mutton soup by the Three Thousand Li River. The mutton soup in Ji 'an is also very good, and the luck of the urban management small market is also ok. The next day, you can go to see Marubi Mountain City and take a taxi to 8 yuan. Pass 100, including General Cemetery and Oriental Pyramid. You can look outside without buying a ticket. It's not interesting. The scenery is very good, and the natural oxygen bar is much bigger than the mountains you have seen in Changchun. It is an excellent place for the photography party. There are three flights from Ji 'an to Changchun all day, at 5: 30 am, 6: 20 am and 14: 50 pm. Well, I've said too much. I don't know if you can understand. Please ask questions if you don't know. Wish you all the best.
