According to the plan, we should go to the base camp first, take a break, and then go to the ice lake after lunch. The Raiders repeatedly mentioned that the base camp has a "bubble wall". When I went, Yubeng hiking was very crowded and the instructions were clear on the way, so I didn't open the hiking software to locate, thinking that I would be done with the crowd. As a result, I missed the base camp perfectly. Reason: There was originally a road to cross the river and walk across the river, but recently the rain was heavy, the bridge was blocked, and the original site of the base camp (including the instant wall) was opposite the river. When I went uphill to the new site of the base camp, the store door was not open (there were not many people at the time), and other travel friends did not dock (many hiking groups brought their own dry food), and then I didn't see the instant wall, and the three of us didn't ask, and went straight forward. After half a child, we felt not right, passing by the people who came down the mountain, told us that you had missed the base camp, only ten minutes away from the ice lake.
