Spring city is full of flowers and cold food. Dongfeng Yuhua Xiehan Food Festival is a traditional festival in China.

There are flowers everywhere in Spring City, which means:

In Chang 'an in late spring, catkins are flying all over the sky, and the east wind blows the willow branches in the imperial garden at the Cold Food Festival.

The date of the Cold Food Festival is just one or two days before Tomb-Sweeping Day. At first, the custom of the Cold Food Festival was not to cook with a fire, but to eat cold food and cooked food prepared in advance, hence the name "Cold Food Festival", which means cold food. However, in the following thousands of years of historical development, customs such as climbing, sweeping, swinging and cuju gradually increased.

The Cold Food Festival originated in the Spring and Autumn Period, and Jiezhi burned in Mianshan, Jiexiu. Jin Wengong ordered a ban on fire and cold food on the anniversary of the child's death, and sent grief with cold food. By the time of the Tang Dynasty, a national statutory festival had been formed, and then it merged with Tomb-Sweeping Day, the earliest traditional festival in China.
