If a person is a very cultured, well-educated, and connotative person, then it will be seen from his speech and behavior. If he is a polite person, he will definitely say thank you after someone helps him. If he is a literate person then he will respond quickly when faced with some problems. If he is a person with relatively high self-cultivation, he will be polite when dealing with others. Try to worry. Although cultural heritage cannot be seen with the naked eye, it is something we can feel when we get along with each other.
