Cixi, also known as Yehenara Xingzhen (1835-1908), empress dowager, Manchu, also known as Empress Xi, Empress Nala, Lafayette, and Empress Xiaoqinxian. The de facto supreme ruler of the Qing Dynasty from 1860 to 1908 lasted for 48 years.
Empress Dowager Cixi, the de facto ruler of the Qing and Guangxu dynasties, lived to be 74 years old (1834-1908). Cixi longevity, in addition to the natural factor of women, is to adhere to the regular diet of medicinal food, from the published 13 tonics, of which Poria medicinal diet use frequency is the highest, reaching more than 78%.

Originally, in order to maintain her health and prolong her life, Empress Dowager Cixi adopted the advice of the Taiyi and ordered the imperial dining room to use fine white noodles and poria powder to make "Poria Cake" as a meal, and often rewarded the ministers with this. Because the poria cake has both a fragrant taste and the effect of dispelling diseases and prolonging years, it has become a famous spot in the court of the Qing Dynasty.
Coincidentally, Cao Xueqin also has a special love for Coco in her famous book "Dream of the Red Chamber". In the sixtieth episode of "Dream of the Red Chamber", "Jasmine powder for rose salt, rose dew attracts poria cream", it is written: Qian Huai's sister-in-law took a paper bag and handed it to the Liu family, saying: Yesterday, a Guangdong official came to worship and sent the first two small baskets of poria cream, and Yu Wai gave a basket to the door as a door gift. Your brother divided these, and last night I opened it and looked at it, weird, snow-white. Say take human milk and eat a bell early every day, the most supplemental. If there is no milk, it is better to use milk, and it is better to boil white water. This "weird, snow-white" thing is poria cream.
Poria cake: Poria poria, rice, sugar each appropriate amount. Poria and rice are ground into a fine powder, mixed with sugar, mixed with water, and spread in a pan over low heat to form a very thin cake, which can strengthen the spleen and nourish the mind.
Poria cream: Fresh poria peeled, refined, sun-dried into white powder. Because the color is like white frost and the texture is delicate, it is named. In "Dream of the Red Chamber", the brother-in-law of the Liu family wrapped a package of poria cream that her husband was on duty and gave to her cowardly and sick niece Liu Wu'er to eat.
