In today's lesson we're comparing the different uses of 让 (ràng)，令 (lìng)，and 使 (shǐ) and we're throwing in a fourth word for you: 叫 (jiào). We'll be talking about which of these words to use in formal and informal contexts. Useful isn't it? We'll also be touching on how to tell someone to do something and how to make them do something. Expect some emotionally-charged examples!
