"Climbing ash" is a figurative swearing word and an extension of the word "picking up ash". If we want to understand the meaning of the word "picking up ash", we must understand the daily utensils of Manchu people in the north-pot stoves. The cooker consists of an upper space and a lower space. The upper space is a burning space and a space for burning hot pot with firewood. Below is the space for ash leakage and storage. In this way, the front of the cooker will inevitably present two holes. People refer figuratively to the female reproductive organs. Before each fire is made, most housewives will rake the ash in the next hole to clean up the ash burned last time. At this time, the grey scorpion represents the male reproductive organs. The older generation joked that this kind of life behavior is "picking up dust". But most of them refer to proper relationship between husband and wife, and jokes account for a lot. Then "climbing ash" is pure swearing; Really point to incest and improper sexual behavior.

The seventh time in A Dream of Red Mansions focuses on the story of the Lord, which is an allusion to the historical event that Boy Scouts suppressed Ao Bai, an elder of the Four Dynasties, in May of the eighth year of Kangxi (1669). After Ao Bai was arrested, he cursed Jiao Taitang, including "climbing the ashes to raise his brother-in-law". Sixteen-year-old Kangxi was still a little emperor, who only knew swearing and didn't know what it meant. I went to ask my grandmother, sourdrang queen, and she gave me a good scolding. The reason is that my grandma and grandpa 14- dourgen (Xiaozhuang's brother-in-law) had an anecdote when they were young. In the book, Feng is the embodiment of Xiao Zhuang, while Jia Baoyu is the embodiment of Kangxi. The author changed the relationship between grandparents and grandchildren to that of uncles and sisters-in-law, making it difficult for readers to attach this content to the history of that year after a hundred years.

Jiao Da publicly scolds the Lord, while Liu Xianglian implicitly scolds the lion, the fourth riddle of fifty-one times-Huaiyin Nostalgia. These three riddles have the same effect. She inspired and warned the prince who was preparing to succeed to the throne and the newly ascended emperor. It is necessary to guard against the old ministers of the former dynasty who add fuel to the flames around the new imperial power, because they have a high position and it is difficult to adapt to the needs of the new era. They must be suppressed by the historical method of "once every emperor and courtier" in order to maintain the consolidation of the new regime. Jiao Da and Ao Bai's names together are "copulation". Homophonic word change-"pride is defeated" This is also a powerful demonstration of the political theme of imperial power in A Dream of Red Mansions.
