For example, in the early years of the Southern Song Dynasty, a folk song said: How many happy families are worried about the moon bending in Kyushu? How many couples are together, and how many are wandering outside? Use contrast to make the differences between the described objects more obvious. This folk song, through the comparison in the front row, describes the pain of people leaving their homes.
Another example is Li Bai's "Visiting Yue Gu": "The Yue King Gou Jian broke Wu Gui, and the soldiers returned home. Maids are like full spring palace, but only partridges fly today. " The poet showed us two pictures: one is that the King of Yue defeated the State of Wu and returned home in triumph. The soldiers all took off their shirts and put on "Jin Yi" to show off their exploits to the people of China. Ladies-in-waiting are dressed like flowers and enjoy themselves in the palace; The other is "only partridges fly today"-there are only a few partridges flying around the old site of the city now, and the victory and excitement of the past have long since vanished. The poem contrasts the prosperity of the past with the desolation of today, expressing the feeling of ups and downs. The use of contrast highlights the theme and makes people think deeply.
