There are a lot of subsidiary industries in the catering industry, and the industry chain is also very long, some of which require technical content, and some of which do not.

From what you've said, it seems that you don't need to have a high level of technical content.

The main business that does not require a high level of technical content is the purchase and sale of business, such as: drinks, beverages, publicity printing, tableware procurement, kitchen equipment procurement, kitchen seasoning procurement, kitchen consumable procurement, kitchen seasoning procurement, kitchen hygiene supplies procurement, work clothes procurement and so on

The business that requires technical content is also a lot of menu production, staff recruitment, chef training and so on, meal ordering service, cleaning tableware ... There are too many.

If you really want to get a good job to make money, get fuel, this thing is still better, not every family can use pipeline gas, that's too expensive. The main thing is that the fuel this thing is not very high technical content, the price has to earn, or the kind of steady income.
