There is absolutely nothing wrong with learning to be a chef. Now the catering industry is very developed. As long as you study hard and really learn your craft well, you will be very popular. Well, the bigger restaurant gives you at least 5000+ a month, just a little tired. Come on! However, I recommend you to study in the school system. Lay a good foundation first, and you will be more satisfied with your work and have a greater chance of promotion in the future!
