It's ok for teachers to eat in 6 yuan. Teachers eat in 6 yuan, which means that in the canteens of some schools in China, teachers can enjoy more favorable food and beverage prices than students, generally around 6 yuan. However, whether children can also enjoy this price concession depends on the specific situation. Children are studying at school, and the school has regulations that allow children to enjoy this price discount, so children can also enjoy the catering price in 6 yuan. However, children are not studying in this school, and the school has no relevant regulations, so children can't enjoy this price concession. Therefore, under specific circumstances, it is necessary to refer to relevant regulations and policies to determine whether children can enjoy the catering price of teacher 6 yuan.
