How is the foil used in ancient poetry?

The use of foil in ancient poetry is mainly to highlight the main things, use similar things or negative and different things as foil, and play the role of "seeing the moon through the clouds". Foil can be divided into positive contrast and negative contrast.

Positive contrast is to set off what is depicted with similar things, set off higher with high ones and set off better with good ones. For example, the Peach Blossom Lake is deeper than thousands of feet, but not as good as Wang Lun. (Li Bai's "To Wang Lun") The friendship with Wang Lun was deepened by the water depth of Taohuatan.

Contrast is a way to use some images to contrast the artistic conception from the opposite side and reveal the main idea. The "contrast" in classical poetry is often manifested in the contrast between dynamic and static (noisy and quiet), joy and sadness (happy and sad), emptiness and reality, and so on. On the comparison between static and dynamic "Bird's Singing Stream" by Wang Wei: "When people are idle, osmanthus flowers fall, and the night is quiet and the mountains are empty. When the moon comes out, the birds are startled, and the sound enters the spring stream. Through the dynamic scenes of "flowers falling" and "moon rising", especially "birds singing", the author not only embodies the quietness and charm of the spring stream, but also makes it never wither, showing its inherent vitality. Dynamic contrast static, dynamic contrast.

Another example is: "On the high banner, six dragons drive the sun, while the distant river below lashes the winding river. The yellow crane can't cross such a high place, poor monkey, only claws can be used. " (Li Bai's "Difficult Shu Dao") The poet wrote that Shu Dao is difficult to travel. From the front, the abrupt mountain above blocked the operation of the sun god; The winding river below is sparkling. Then he drew a stroke and compared the yellow crane with the ape. Flying thousands of miles, yellow cranes are not allowed to fly, and agile apes are also worried about climbing. It goes without saying that it is more difficult for people to walk, and it is difficult to write Shu Dao in both positive and negative ways.
