On February 2nd, the dragon looked up and ate: spring cakes, jiaozi, mixed dishes and noodles.

Since February 2nd is the time when the dragon looks up, many foods are associated with dragons.

In Beijing area, people eat more spring cakes on this day, which is called "eating Long Lin", and they are more particular about eating with "combined dishes". The combined dish is made by frying shredded lean meat with spinach, bean vegetables, garlic and other vegetables. When eating, the spring cake is divided into two parts, covered with sweet noodle sauce, served with green onions, then sandwiched with the combined dish and rolled into a tube.

Noodles and dumplings are also popular in northern areas.

The agricultural proverb "On February 2nd, the dragon looks up", it is said that in ancient times, there was no rain in Guanzhong area for a long time, and the Jade Emperor ordered the East China Sea Xiaolong to sow rain. Xiaolong is playful and dives into the river and never comes out again. A young man went to the cliff and collected "dragon water" to muddy the river. Xiaolong emerged from the river to compete with the young man. Xiaolong was defeated and had to sow rain. In fact, the so-called "dragon looks up" means that after hibernation, all insects begin to wake up. Therefore, as the saying goes, "On February 2nd, dragons looked up, scorpions and centipedes all appeared." Eating beans in Shandong rural people say: stir-fry scorpion claws to ward off evil spirits and pray for blessings.

Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
