The lyrics of this theme song are extraordinary, rich in connotation, novel in wording and full of philosophy. Lyrics and songs are integrated, with women's complaints and men's vigorous breath, like the aging of the years, spicy with sweetness and bitter with fragrance; There is not only a look back on the past bitter days, but also a pleasure and enmity in suffering. There are both struggles against injustice in life and praises for kind people and things; There are both the lashing of ugliness and the pursuit of light. The tune is catchy and approachable in sadness. It has a potential power to support people to move forward on the still complicated and bumpy road of life, and to "carefully consider the past and the future". Pursue a sincere life. So it is deeply engraved in the memory of the audience. "There have been joys and sorrows. Why are you so persistent? " This kind of "exhortation" question is really intimate for people with high understanding and people who can't finish thinking with others. This is also the artistic charm of this song.
