There is no chicken, duck and fish, only vegetables and tofu are indispensable.

Ancient people wrote articles without punctuation, which caused a lot of trouble to future generations and of course left many jokes. For example, a teacher tutors a rich man. The listed condition is "Don't eat chicken, duck, fish or just eat vegetable tofu." As soon as the landlord saw it, he said, "Chicken, duck and fish are all unnecessary, only vegetables and tofu are indispensable, and you can't spend a penny." It's good. Just hire him. Soon, the teacher raised an objection and the rich man said, didn't you write it? Mr. Wang said, what I wrote was "no chicken, no duck, no fish and no meat, only vegetables and tofu, and no penny."
