1938 at the commemoration of the second anniversary of Lu Xun's death in Wuhan, he said, "I may be a family member of Mr. Lu Xun by blood, because I was born in Zhoujia, Shaoxing City, Zhejiang Province." 1952, Zhou Enlai said to Xu Guangping, "I will call you aunt from generation to generation." On 1969, I said to Zhou: "I checked, you are the twentieth grandson of Shaoxing Zhou family, I am the twentieth grandson of Shaoxing Zhou family, you are my elder, I want to call you uncle!" It is estimated that one of his family members or relatives "checked" what the record told Zhou Enlai, but found no such clear record. However, Zhou Enlai's statement has aroused the interest of many researchers. In the study of Lu Xun's family relationship with Zhou Enlai, there are three outstanding figures: Mr. Zhang Nenggeng, Mr. Qiu Shixiong and Ms. Wu Changhua. Zhang Nenggeng served as the director of Shaoxing Lu Xun Memorial Hall in 1950s, studied Lu Xun for decades and published books such as Lu Xun's Youth. In recent years, Zhou Enlai's Family History and Lu Xun's Family History, which he co-edited, are the works of emperors, with rich historical materials and heavy academic weight, which describe the ins and outs of the two families clearly and attach various detailed genealogy tables. Qiu Shixiong has been the curator of Shaoxing Luxun Memorial Hall since 1980s. He has also studied Lu Xun for more than 20 years, and published works such as "Picking up Shells on Land and Sea" and "Picking up the History of Literature". There is an article "Two Questions about Lu Xun and Relationship" in "Picking up Shells in Luhai", which makes the two families clear with refined pen and ink, and lists two family tables at a glance. Both Zhang and Qiu believe that Zhou Ao, born in 1263, is the ancestor of Shaoxing Qifu Bridge and Shaoxing Yuhua Bridge, which Lu Xun belongs to. Zhou Aosheng has four sons: Zhou De, Wan Yi, Wan'er and Wan San. Lu Xun was after Zhou De, while Zhou Enlai was after the first year. Qiu Shixiong pointed out that according to the existing historical data, the lineage from Zhou 'ao to Zhou Enlai is clear, such as Zhou 'ao as 1 generation and Zhou Enlai as the 24th generation. However, the lineage from Zhou Ao to Lu Xun is not clear, because Lu Xun's reciprocal 14 generation, that is, Zhou, is clear, and the number of generations between Zhou Ao and Zhou is lacking. Therefore, under the current conditions, it is impossible for Lu Xun and Zhou Enlai to be ranked according to their seniority. Then Wu Changhua came out. Wu Changhua is a researcher at Lu Xun Memorial Hall in Shanghai. He published monographs such as Biography of Feng Xuefeng, and published several research papers on Lu Xun. She published the article "With Lu Xun" in the 9th issue of "A Study of Lu Xun in Shanghai" published on 1998, and thought that since Zhou and Macao were found to be * * * ancestors, their family background with Lu Xun was clear. At the end of the article, she listed a list of the lineages of Lu Xun and Zhou Enlai, in which Zhou Ao was 1 generation, Lu Xun was the 23rd generation, Zhou Enlai was the 24th generation, and Lu Xun happened to be an uncle. She didn't explain how her genealogy was listed. Probably according to the statement, Lu Xun is an uncle, so she locked Lu Xun in a higher position, and then started with Lu Xun in a "reciprocal" way, drawing a line from Zhou Ao to Zhou Ao, and the table was made. As for the question of how many generations there are from Zhou ao to Zhou, she didn't mention it in the article, only noted the word "unknown" in the table. How long is the interval from Zhouao to Zhouyizhai? Zhou Ao was born in 1263, and his eldest son Zhou De was born in 1280. The date of birth is unknown, and his wife Zhao was born in 1489. The age of husband and wife is roughly the same. From 1280 to 1489 * * 209, although the word "unknown" is indicated in Wu Changhua's Genealogy Table of Luenlai in 2009, the reference genealogy table must be eight generations, so her two comparative genealogies can be established. In 2009, it was divided into 8 generations with an average interval of 26. 1 year. This age is generally acceptable, reasonable and not outrageous. This cannot but be admired: The Genealogy Table of Lu Xun and Zhou Enlai, which Wu Changhua boldly and quickly drew up, is extremely creative and of great reference value. However, history is concrete. The average can only "roughly estimate" some historical phenomena and cannot accurately explain historical facts. Early marriage was very common among wealthy families in feudal society. If the average generation interval is 23 years old, then 209 becomes 9 generations, and Lu Xun becomes 24 generations, which is equal to Zhou Enlai. If the average generation interval is 2 1 year, then 2009 is almost 10 generation, and Lu Xun becomes the 25th generation. On the contrary, Zhou Enlai is an uncle and Lu Xun is a nephew. Someone once said that 30 years is a generation. If the generation interval is 29 years old, then 209 is the seventh generation, and Lu Xun becomes Zhou Enlai's great-uncle. What's more, when it comes to specific people, the age range of each generation can be said to be varied. For example, Lu Xun's father was born at 2 1 year old, and the difference between them is 20 years old; Lu Xun himself "got a son at fifty", and his distance from Yinghai was 48 years old. If calculated by "average", their father and son are counted as three generations. Therefore, 2009 is still an unknown number of generations; Which generation of Zhou Enlai was Lu Xun? Granduncle? Uncle? Peer? Nephew? It is really impossible to draw a conclusion, and it remains to be further explored by historical materials. Recently, I read Wang Xirong's The Mystery of Lu Xun's Life. The first article is about the relationship between Lu Xun and Zhou Enlai. Originally, through the efforts of several researchers, the ins and outs and crux of this problem have been very clear, but by Mr. Wang's pen, it has been written very complicated. "Tangle" has almost become the "feature" of this book. As for what Mr. Wang wrote, the author talks about three points here: 1. In the article, Mr. Wang clearly stated: "We can't clearly and accurately draw the whole pedigree table from Zhou Dunyi to Lu Xun" and "we can only expect new data to be found to solve the problem", but he still listed Lu Xun's pedigree table at the end of the article and wrote the relationship between Lu Xun and Lu Xun. Neither the front nor the back of the table shows that this table is just a statement in academic discussion. The author reminds readers here: Please don't think that Lu Xun and Zhou Enlai are really uncles; Please pay attention to the problem of "passing mistakes by mistakes".
