Jia Jian is a sad and touching love poem, which vividly depicts the psychology and feelings of an infatuated person.
The first sentence, "Jian Jian Cang, Bai Lou is frost", depicts a late autumn scene with heavy frost. The poet went to the river to pursue his sweetheart on a bleak autumn morning. He seems to see his sweetheart on the opposite side of the water, so he "follows it" and pursues her upstream, but the road is difficult and far away.
The poet wants to get close to his sweetheart, but he can't. He can only wander by the water, and his sweetheart is beyond his reach. From this, the poet depicts a hazy artistic conception and obsessed mood, and creates a confused and sentimental mood, which is extremely infectious.
Supplement:
The technique of repeating chapters and singing in Jianjia is a common expression in The Book of Songs, which is very suitable for expressing feelings.
