He Yisheng xiaojimo last line is since the qin and se is from Gu Man's novel "He Yisheng xiaojimo". The full text is as follows: Since you don't look back, why don't you forget since there is no destiny, why do you need to swear? Today, all kinds of things, like water without trace; tomorrow night and night, you have strangers. The fate has always been shallow, but why the love is deep? Since the zither up, why the sheng xiao mime a song of the zither according to the fragrance of the flowers, ten thousand lonesome dyeing neon dress.
Explain that since you choose to leave, do not say that you will not forget; since you and I are not destined to be together, there is no need to swear, because it is useless to swear more.
何以笙箫默一曲琴声依花香句子的描述今天的一切，就像水流过一样不留下痕迹。 After tomorrow, when we see each other again, we will become strangers played a lute, the mood feels very lonely, can only dance according to the song.
There is another interpretation, meaning probably, the sound of the qin and sepals have come out, why the pith is still silent. So, my personal understanding is that since we have started, how can we bear to end up with no result.
It is supposed to express a kind of steadfast perseverance in love, no matter how many dangers and obstacles, never give up of course can also be interpreted as a kind of confidence in love, the future to put a good prayer believe that the two people can overcome the difficulties, hold on to their love, and create the most brilliant harmony.
