Take a cruise boat and visit the magnificent Lake Baikal. It was cold and windy on the lake. We were all very enthusiastic, boarding a boat and getting close to the beautiful Lake Baikal. The deepest part of Lake Baikal is more than 1642 meters, the lake shoreline is more than 2500 kilometers long, the widest part is more than 80 kilometers, and the lake is 636 kilometers long. The azure blue sky, sometimes densely covered with thick clouds, adds to the mystery of Lake Baikal. Language can't describe. Come on, only by being in it can we truly feel the beauty. The ear seemed to echo Li Jian's "Lake Baikal" and he was reluctant to leave. Next time I'll take a deep tour, I'll only come here for eight days and nine days.
