What does Lake Behar mean?

Lake Baikal is just an image. In everyone's mind, it may be Tibet, Yunnan, Dali, or even a park swing with a loved one. After many years, things have changed, and the people around them are no longer the people who have thought about it all their lives. When they think back to the place on the shores of Lake Baikal where they left deep feelings, they think that there is probably too little time to keep their promises in this life. This is also the reason why so many people are moved. This is a song.
