It is said that the custom of inserting willows is also to commemorate Shennong’s farmer’s ancestor Shennong’s. In some places, people put the willow branches under the eaves to forecast the weather. The ancient plaques have the sayings of "wicker green, rainy, dry wicker, and clear weather." When Huang Chao was uprising, it was stipulated that "the Qingming period is the end, and the Dailiu is the number." After the failure of the uprising, the custom of Dai Liu was gradually eliminated, and only the insertion of the willows was not bad. Yangliu has a strong vitality. As the saying goes: "There is no heart to plant flowers and flowers, and there is no intention to insert willows into the shade." Wicker soil will live, where to insert, where to live, insert the willow every year, everywhere into the Yin.

Influenced by Buddhism, people think that Liu can be a ghost, but it is called "Ghost Terror Wood". Guanyin uses the willow branches to absorb water and benefit all beings. In the Northern Wei Jiasi's "Qi Min Yao Shu" said: "When the willow branches are placed on the house, the hundred ghosts do not enter the house." Qingming is not only a ghost festival, but in this wicker season, people naturally insert Liu Liuliu to ward off evil.

Li Bai has a word cloud: "Years of the year, Liuling, and Fuling." On both sides of the ancient Chang'an Bridge, the embankment is ten miles long, one step at a time. People from Chang'an East go to this place to say goodbye, and the willow branches are given to other relatives because of "Liu "Harmonize" with "remaining" to indicate the meaning of retention.
