The content of Sun Yat-sen's book about Li Hongzhang is mainly to develop agriculture, industry, commerce and learning. For the people to be rich and the country to be strong. It can be seen that at that time, Sun Yat-sen, as a warm-blooded young man, had a valuable spirit of caring for the country and the people. That's good. But doesn't Li Hongzhang know these things? It's easier said than done. Later, Sun Yat-sen himself became the interim president and prime minister of the Republic of China. Set state power in one. I don't know how much power Li Hongzhang has. How many things did he do in this letter? ! As for why Li Hongzhang didn't adopt it. I don't think Li Hongzhang is likely to see this letter. I don't know how many such letters he received. Sun Yat-sen was just a young doctor in his twenties. Because he was Sun Yat-sen, he later became a climate. So now we know there is this letter. I don't know how many letters Li Hongzhang received at that time were more insightful than him. We just don't know. We have to adopt them one by one. Isn't that great? Don't mention that time. Now is such an open era. You wrote a letter to the Deputy Prime Minister. Put forward comprehensive suggestions on national policies. This should be like this and that should be like that. Who will talk to you again? :).
