Earn money in general, mainly training fees and class fees. If you are a gold medal lecturer, it may be ok, but the workload is very large, which is in direct proportion. If it is unrealistic to make a lot of money, after all, the soft clothing industry is too common, and there are many related training institutions, so the opportunity to make money can be imagined. Don't think too well of this plate.
In addition, the development of the whole construction industry is slowing down at present, but the number of new talents in the industry has never decreased. Although there are many training opportunities, it is of little use to newcomers, and it is naturally not easy to make big money as a trainer.
