It happened that there was a chef in the palace who was born in a peasant family. Knowing that the queen ate more delicacies and meat, she put some handmade noodles in the cool egg soup, accompanied by minced meat, chopped green onion, shredded ginger, egg cake and so on. This is seasoned with aged vinegar. The Queen of Gong Zheng even ate several bowls. The emperor was overjoyed, tasted it himself and praised it while eating. When eating, the emperor saw that the vegetables and vegetable oils in the bowl were yellow, white and green, and the colors were distinct. He picked up the noodles to look like flags, and then put them in a bowl to look like flowers. Ming Xiaozong named them flag flower noodles and listed them as imperial meals.
Later, Kang Hai was the number one scholar in Hongzhi period, edited by imperial academy. He is a martial artist and likes noodles. Let his chef learn to make a flag face from the chef of the royal chef. After being dismissed from office, he took the chef back to his hometown, so the flag flower noodles spread in the martial arts. For more than 700 years, the flag-painted face has been circulated in Wushu.
