"Lake Baikal" took me into a different world, where the ground was full of snowflakes, so pure that it made people yearn for it. "The Book of Yesterday" is about meeting love at a place deep in the forest where you see a deer, hoping that all the love affairs in the world will go well. "Ideal Thirty" tells the story of the years in sad songs.

In addition to popular pop songs, there are also some folk songs that have been popular on major charts in the past two years. The melody of the ballad is gentler than other songs, and the language is simple but not monotonous, and the songs are sung with strong colors. Moreover, the content of folk songs is very broad, not limited to one theme, and covers all aspects of life. It shows the unique emotions, habits and admiration of each nation, highlighting the uniqueness of this nation.

"Ideal Thirty" I like this intro very much. It goes directly to the theme without any delay. In this song, Chen Hongyu sings about the kind of pursuit of ideals for half a life, an understatement of the past life, and the indifference to the future life. "Book of Yesterday" is a song that a person will listen to when he is lonely. A boy once shared this song with me. I really like the character in it who dares to see through but dare not care. Isn’t that how people deal with relationships nowadays? I want to go further, but I am afraid to take this step.

In the end, after going round and round, I found that I had lost the most sincere feelings. Li Jian used his unique voice to sing "Border of Lake Baikal", recreating the beautiful scene of Lake Baikal in the cold winter before our eyes. The frozen world is so beautiful that it is intoxicating. Listening to this song is like a spiritual pilgrimage, which can cleanse away all the filth in your heart.
