In 1823, the year of Guiwei, few people knew about his birthday! Don't tell me the time! Baidu Encyclopedia, the complete biography of Hu Xueyan, I didn't find it written. I bought a book "The Complete Biography of Hu Xueyan" edited by Liu Yifa. I read it carefully and couldn't find it! If you know it, tell me by the way. QQ1297905803 Thank you! I also admire him very much. As the saying goes - if you are doing business, you should read "Hu Xueyan"; if you are doing politics, you should read "Zeng Guofan"!
