The third stage of severe cold is that Shui Ze's abdomen is firm, which is the last stage of 72 stages. "Shui Ze's belly is very strong" means that the ice on the lake has frozen firmly to the center of the water. It's very cold. According to the principle that extremes meet, spring water comes from the depths of hard ice, and when it is extremely frozen, it will melt. "Xiang Shuo gua qi seventy-two years later": "move up and Kun becomes a root. Gen is the abdomen, Kun is the abdomen. Gen operator right, right for, called Kun for. It is powerful. " "Twenty-four solar terms": "The sun is not up, the east wind is not up, and Shui Ze is forging ahead." "When the ice started, it was just on the water. At this time, it has completely condensed, so the cloud abdomen is firm and the abdomen is still inside. "
"Book of Rites and Moon Order": "(Winter Moon) is full of ice, and Shui Ze's abdomen is firm, so it is necessary to take ice." Zheng Xuan's Note: "Abdominal, thick." According to the press, Sun Xidan summed it up like this: "The abdomen is the depth of the water, and it is said to be in the water. If a person's abdomen is natural, it will gradually reach the bottom from the top, even the moon, and Shui Ze's abdomen will be condensed and strong. " Teacher Yi Zhoushu said, "Shui Ze has a strong stomach." You Zhu once explained: "The abdomen is solid, and the ice is as solid as the abdomen." Han Zhang Hao's "Zangbing Fu": "When you are twenty years old, you will know that the ice belly is strong." Ming Gui Youguang's "Ren Xu's Journey" said: "When I hear that the ice of the Baihe River is still firm, I must go by land." In the last five days of the great cold solar term, the ice in the water has frozen to the center of the water, and it is the strongest and thickest. At this time, it is also the time for the body to study hard. Although nature is "the belly of the ice pool is firm" and the water in the pond weir enters a state of belly firmness, what should appear in the belly of human self-cultivation health-preserving people is not the ice firmness of water, but the firmness of water, even the firmness of Dan, which is just the opposite phenomenon.
Hua Xinfeng is a mountain alum in the third great cold period. Huang Tingjian, a writer in the Song Dynasty, once described it like this:
"In the Ye Nan, there is a small white flower, which is several feet high, and the spring scenery is very fragrant. The savage is Hua Zheng. Wang tasted this kind of flower and wanted to write a poem, but he read its name. He invited Mingshan Alum. The savage used Huazheng to dye yellow, and did not use alum to make color, hence the name alum. "
Alum is produced in Jiangsu, Zhejiang, Fujian, Taiwan Province, Guangdong, Guangxi, Jiangxi, Hunan, Hubei, Sichuan, Guizhou and Yunnan. Nepal, Bhutan and India also have it. Born in the forest at an altitude of 200- 1500m. Roots, leaves and flowers are medicinal; Leaves can be used as mordants. Among them, the common alum is mostly used for landscaping and desertification vegetation greening.
It is also recorded that Alum Mountain is the lost famous flower "Yuruihua" in the Tang Dynasty. In Qing Dynasty, Hong Mai said in "Rong Zhai Essays" that "things are rare and expensive, so there is no need to be heterogeneous. Chang 'an Tangchang stands for Yu Rui, which is a modern flower, also known as rice sac, and Huang Luzhi is Yishan alum. "Huang Luzhi is Huang Tingjian, Lu Zhi is his word, and he claims to be a Taoist priest. Formerly known as Yu Rui, it was later renamed Shanfan because of Huang Tingjian.
