As the saying goes, an apprentice is a slave for three years. In the eyes of many people, being an apprentice is to learn from the master and improve their practical level through learning. In fact, there is a big misunderstanding. Take learning to be a chef as an example. The first thing a novice hotel apprentice should do is to "respect the teacher" as the ancients said-bring tea and water to the master and always "honor" the master; Secondly, as an apprentice in a hotel, he became a cheap labor force in disguise. Waiter, side dishes, washing dishes and so on. It's all done by apprentices, which is why many former apprentices complain about being tired. Finally, learning from chefs, focusing on practice, rather than the secrets of martial arts passed down from mouth to mouth, requires real practice. However, the hotel is not a good hall, and opening the door to do business pays attention to economic benefits. It is impossible to provide free ingredients for apprentices to practice, resulting in many people's poor cooking skills after several years of apprenticeships in hotels.
