The day before in Tomb-Sweeping Day was the Cold Food Festival. Fireworks are not allowed to be set off at the Cold Food Festival, and only cold food and cold dishes can be eaten to commemorate the aristocratic meson push of Jin State in the Spring and Autumn Period. Meson push, also known as meson push, meson push. He went into exile with his son Zhong Er (later Jin Wengong). After Wen Gong returned to China, he rewarded his followers. Jiexiu was not rewarded, but lived in seclusion with his mother in Mianshan (that is, Jieshan in the southeast of Jiexiu County, Shanxi Province). Later, Wen Gong wanted to give him an official title, but he refused. Wen Gong had no choice but to let Yamakaji go. He tried to force him out, but unexpectedly, he burned the mother and son to death in the mountains. Later, due to the connection between cold food and Qingming, it gradually merged into a festival, but the custom of steaming "pushing buns" before the festival has been spread in Yulin and Yan' an in northern Shaanxi.

"Zituimo", also known as Lao Momo, is similar to the helmet of ancient military commanders and weighs about 250 yuan. 500 grams. Eggs or red dates are wrapped inside and have a top on them. The top is covered with flowers. Hua Mian is a dough-shaped steamed stuffed bun with the shape of swallow, worm, snake, rabbit or Four Treasures of the Study. The round "push buns" are for men to enjoy. Married women eat long "shuttle buns" and unmarried girls eat "catch buns". Children have flowers such as swallows, snakes, rabbits and tigers. "Big Tiger" is specially for boys, and it is also their favorite. Parents string various small flowers with pear branches or fine twine and hang them on the ceiling of the cave or next to the window frame for children to enjoy slowly. Air-dried noodles can be stored in Tomb-Sweeping Day the following year.

Making flour flowers is a specialty of women in northern Shaanxi. With their dexterous hands, they can knead fermented white flour into flour flowers of various shapes. Tools are just daily necessities such as combs, scissors, awls and tweezers, and accessories are red beans, black beans, peppers and food pigments. Steamed noodles are lifelike, especially like art treasures, which makes people reluctant to eat them at once.

"Zituimo" and flour flowers are not only eaten by themselves, but also given as gifts to relatives and friends. When a mother wants to give it to her daughter who got married that year, it is called sending cold food. Children in rural areas give them to their teachers, so that gardeners who leave home to teach and educate people in remote mountain villages alone can share holiday food.
