How to praise strangers

For strangers, we can roughly judge the scope of things they are proud of from their occupation, environment and historical period. A general is often proud of his outstanding military achievements. A learned scholar must be proud of his published papers and monographs. If you want to praise a strange scholar, you may as well say to him, "Sir, your papers and monographs have a great influence in the academic field. I have heard a lot about them." Lawyers will be proud of handling influential cases by themselves. When they come across a lawyer, they can say, "the people who are lawyers are not simple. Many cases you handle are excellent." Even if he is a farmer, he will have a sense of success because this year, he is the only one who has planted sweet potato, and the sweet potato market is surprisingly good. When you buy sweet potato, you may as well say: "brother, you really have insight, this year's sweet potato market is to let you see."
