Half a century ago, there were many Xiao's, but few Xiao's. After the promulgation of the First List of Variant Characters and the Simplified Scheme of Chinese Characters, many people think that Xiao is a variant of Xiao, or that Xiao is a simplified character of Xiao. Therefore, many people with the surname "Xiao" write "Xiao" for simplicity; The staff of some departments often write Xiao as Xiao when they go through the formalities of identity card, household registration and admission for people surnamed Xiao. Therefore, in recent decades, the surname Xiao has increased. In history, there was a small country called Xiao, which was a vassal state of Song in the Spring and Autumn Period. There were two small dynasties in the Southern Dynasty, the emperor surnamed Xiao and Qi; Xiao in Tang Dynasty and Xiao Dezao in Song Dynasty were all famous historians of Xiao literature, and Xiao family scholars in Southern Dynasties also made great achievements. Most people think that "Xiao" is a simplified word for "Xiao", but there is no such thing. There is no "small" abbreviated as "small" in the simplified Chinese word list published by the state, that is, "small" cannot be abbreviated as "small". The author treasured a personal letter from Mr. Shang Chengzuo, a famous philologist. There is neither a traditional Chinese character nor an irregular simplified Chinese character throughout. The possible basis for using Xiao is Xinhua Dictionary: "Xiao (surname) is commonly known as Xiao. Compared with Xiao's custom, Xiao is really elegant. Kong Zhi's "Wen Yi in the North Mountain": "The husband took Geng Jie as the standard to pull out the customs, and he sprinkled the dust. "Cui Jiao's poem" Seeing the Maid Off "says:" Once in Houmen Sea, Xiao Lang is a passer-by ",and" Xiao Lang "generally refers to the man a woman loves. Similarly, "little Niang" can be compared to a woman. Zhou Bangyan's "Night Tour Palace" says: "Whoever has a cloud, a book is a piece of paper for Xiao Niang. "China law stipulates that citizens have the right to use their own names. Radish and vegetables have their own tastes. Originally, Xiao and Xiao can suit both tastes, but in reality, they can't. I remember that Mr. Xiao Yu from the Ministry of National Machinery went to Germany to negotiate with the author and decided to go to Macau temporarily. When the Foreign Affairs Office issued the exit certificate, I doubted that all the forms I filled out were "small" and checked Xiaoyu's passport in time. The Foreign Affairs Office is afraid that we will get into trouble when going abroad. With experience, this possibility will exist. Why do you say "Xiao" is "Xiao" In fact, the history of "Xiao" and "Xiao" confusion is not very long so far. I didn't find it in Zhongshan when I was a child. It was only after the Cultural Revolution that "Xiao" became more and more popular. Now there are so many people named Xiao in the phone book that the word "Xiao" is simply "leaving none" on some occasions. The reason is that misunderstanding from outside is a factor. In the final analysis, it is still Xiao's own business.
