Thanks to Yang Guifei and Supplement to Tang Poems and Palace Poems, Ejiao has gradually become a beauty product favored by the world after Yang. However, due to the prominence of the Tang and Song Dynasties, ordinary large families can only ask for trouble and toss and turn. It was not until the Yuan Dynasty that the status of Ejiao was loosened and spread outside the palace. Unexpectedly, this small step from the palace to the outside of the palace has also become a big step for Peach Blossom Ji's thousand-year journey. For a time, the skill of Ejiao beauty became a common practice. Large families who have the ability to find Ejiao have begun to study various eating methods of Ejiao. Among them, one method was most favored by rich women and good girls, so that it was widely sung in the works of Bai Pu, one of the four great masters in Yuan Dynasty. There is a cloud in his "Autumn Night Buttontree Rain Flowers on Brocade": a bowl of donkey-hide gelatin, a sesame seed and a red stuffed candied rice. Pink cheeks are like shame, apricot flowers and spring rain are smiling. Moisturizes youth, saves years and gains capital. Ejiao meets sesame, just like Boya meets a child, and soon "bumps" into a piece, and then becomes a beauty. Its principle can't be verified by people at that time, but it doesn't affect the beauty recipes of Ejiao and Sesame as the hometown of Ding cuisine. By the end of the Yuan Dynasty, the momentum of this cookbook had not disappeared, but intensified, involving the customs of a place. The beginning of the story is unsurprisingly related to love. In the Yuan Dynasty, there was a big family named Liu in Zhejiang, and there was a little girl at home. It happened in the 1920 s and 1980 s, with a mouthful of Dan and no eyebrows, needless to say, beauty, and relatives and friends stepped on the threshold. By chance, Miss Liu met a poor scholar and chatted happily. The friendship between the two people is growing day by day. Later, it developed to the point where "non-gentlemen don't marry". In ancient times when the concept of family was very strong, it is conceivable that Miss Liu's parents must be a hundred unwilling. In all kinds of helplessness, Miss Liu chose to elope with the poor scholar. But I don't know why, since this Miss Liu left angrily, her face is getting haggard day by day, and she can't find any trace of Hao Xue's obesity at the beginning, but she doesn't feel any physical discomfort. Miss Liu, after much deliberation, attributed the reason to the donkey-hide gelatin and sesame seeds that Cardamom used to save lives when she was young. She told her husband this conclusion. The speaker is careless, and the poor scholar loves his wife. On the one hand, he wants to take care of his wife, on the other hand, it is really difficult to get Ejiao on his own terms. After careful consideration, I took an adventurous move-sneaking into Miss Liu's parents' house to find Ejiao. However, as a weak scholar and nervous, he was discovered by Liu's servant in the process of groping. In the dark, he gave the scholar a disorderly stick without careful identification, and his body was not strong. Plus this beating, the scholar died on the spot. Later, the big family here could not help but take this as a warning. When their daughter gets married, no matter whether the married person is rich or not, they attach a few pieces of Ejiao as a dowry. Over time, this has also become a custom in Jiangsu and Zhejiang provinces.
