The weather in Luding is 30 days.

Gan Yu did not want to escape during the earthquake, but chose to open and close the gate to protect the downstream villages. Later, he got lost in the mountains and survived by eating wild fruits. Finally, he was found by a villager and received treatment. Gan Yu is a very ordinary worker, but he has done extraordinary things. One action saved countless lives, but he himself was in danger.

At the first time of Luding earthquake, many people's first reaction was to flee to a safe place as soon as possible, but Gan Yu and his colleague Luo Yong didn't. They rushed to the dam as high as 10 without thinking, and pulled the floodgates in time to prevent the downstream villages from being flooded by the river. At that time, the situation was very critical, and the mountains on both sides could slide at any time. After a night's rest, the two decided to run away as soon as possible. In this process, Gan Yu was separated from his colleagues because of physical exhaustion.

Luo Yong was finally rescued after being trapped for three days, but Gan Yu was never found. Qi Xin, a multi-party rescuer, made concerted efforts to rescue Gan who lost contact as soon as possible. However, due to the rainy weather, the helicopter could not rescue normally, so rescuers had to hike up the mountain. Unexpectedly, the rescue was forced to stop again because of the road collapse. Fire brigade, professional rescuers, guides and other people formed a rescue team to carry out search and rescue, but he was never found.

Everyone is worried about the rain. After all, we have lost contact 10 for more than a few days, and the situation is not optimistic. After learning about this incident, a local fellow villager went into the mountains with food and clear water to look for it, and finally found the rain that had been lost 17 days, and took him home. After examination and diagnosis by doctors, although Gan Yu is weak and seriously injured, his overall vital signs are stable and conscious, and he needs timely treatment and rest. This story touched many people. Gan Yu didn't run for his life for the first time when he was in danger, but really sacrificed himself for others, thanking him for his contribution to countless villagers.
