If the first issue of "Seeds" is written by Wang Sulong from an individual to write the hearts of ordinary people, then this "eccentric" is extremely personal and self-centered. Talking about this "eccentric" song, Wang Sulong said: "I have sung many songs, and this song is for myself." "I live in a very homesick life, and many people will feel uncomfortable." "When night comes, I feel bad and unhappy." "Anyway, I am used to regretting and good at helplessness." Between the lines of the words, Wang Sulong's affectionate self-description, like mumbling to himself, shows vividly the frustration, weakness and even affection in life.
