A man in Kunming lost contact in Dali for five days. How is the police search and rescue operation going?

On August 2 1 day, Li Tao, a young man from Kunming, checked into a hotel in Dali alone. On the morning of 22nd, he went out with his bag on his back, and never returned to his room on the evening of 22nd. By August 26th, he had been missing for four whole days. His family rushed from Kunming to Dali, looking for him everywhere. Finally, with the help of the police, it was speculated from the monitoring of the inn that he climbed Cangshan on foot. His father is very anxious, hoping that someone who has seen his son can provide information. According to his description: Li Tao is 1.75m tall and weighs about 62kg, which is a little thin. When traveling, he wore a light blue-green coat and carried a gray-red backpack.

With the cooperation of the local police, through the surveillance video of the inn, we can infer Li Tao's action trajectory:

At 22: 30 on August 2 1 day, Li Tao checked into Dali Binya Hotel Co., Ltd. (Home Inn) and booked two nights on August 2 1 day and August 22. However, he didn't eat enough.

At 6 o'clock in the morning on the 22nd, Li Tao went out with his bag on his back, and didn't return to his room until the evening of the 22nd. Small sundries such as laptops were picked up at the front desk of the hotel.

On August 27th, Datang Ranger, the leader of Dali Red Star Outdoor Sports Association, who led 12 team to search for the lost Kunming tourist Li Tao in Dengcang Mountain, found Li Tao's hiking bag, hiking shoes and mobile phone, and informed him that Li Tao had passed away, which was confirmed by his family and the police. Red hiking bags, hiking shoes and mobile phones were found between Malong Peak and Shengying Peak, and the trapped people were found to have no vital signs near the items.

Li Tao's father, Li Wei, is 65 years old and Li Tao is the only child. On 27th, when the rescuers went up the mountain, Li Wei accompanied them to Gantong Temple, waiting for the news that his son was rescued.

After the news of Li Tao's death came back, the local police specially visited Li Tao's parents and relatives who came to Dali. ? The road up the mountain is too steep for search and rescue personnel to go down the mountain empty-handed. The work of carrying the remains is done by the police. Tomorrow we will go directly to the funeral home to see people. ?
