People who enter the chef's business can generally use their lunch break to go to the bookstore to read books about cooking, and don't buy them, because cooking books are relatively expensive (it's not easy to save money), and wait until they think the books are really good. Generally speaking, you can read books on basic cooking skills (knowledge of raw materials, processing of raw materials, cooking techniques), cooking of eight major cuisines, local dishes, innovative dishes, competition dishes, etc., which can greatly enrich your knowledge. You'd better take some notes (so that you can refer to them). If you persist in this way for several months, it will be better than spending money on training courses. You will definitely make a name for yourself in cooking, and your career success is in front of you.
