Similarities and differences between foil and foil: the same thing is that there are primary and secondary points between the listed things, all of which are to emphasize the characteristics of the main things. When there is more than one thing listed in the two methods, both methods can generally be used. However, foil is only a specific form of foil. If one thing implies another thing, the main thing may not be explained. The foil is that these two things have to be explained and set off each other. Contrast must use a number of secondary things to highlight the main things. Contrast can be one-to-one or many-to-one.
What needs to be added is the similarities and differences between positive contrast and negative contrast. These two predictions are two concrete applications of foil technology. Positive contrast refers to setting off things with the same nature or characteristics. For example, Du Fu's quatrains: "The whiter the Jiangbi bird, the blue and white mountain flowers will burn. I saw it again this spring. When is the year of return? " With "Jiangbi", "Bird White" and "Mountain Blue" as the background, the colors are in harmony with the scenery. Contrast is to use the opposite of one thing to set off another. This technique is widely and typically used in lyric poetry to borrow scenery, which can be roughly divided into: writing mourning with pleasure scenery and writing mourning with Syaraku scenery. The former, such as Ouyang Xiu's Walking in the Sand, uses the beauty of spring to set off the poet's parting feelings; The latter, such as Li Bai's Xia Sai Qu (Five In the snow in Tianshan Mountain), expressed the optimistic revolutionary feelings of the soldiers guarding the border with the help of the harsh environment in Tianshan Mountain.
