Want to recruit a chef, a chef.

Start with your friends and ask them if they know any friends who are cooks. If so, tell them that you want to find a chef and ask them for help.

Direct search:

Go directly to the hotel restaurant to find the chef (usually the chef, because the chef's contacts will be slightly better than usual, and he will know more), tell him that you need some chefs and ask him if there are any chefs who are temporarily absent from work. If so, ask him to introduce you (generally speaking, he will be happy to introduce you, which is related to the characteristics of the chef industry. But there are also some people with bad personalities, just treat them as garbage)

The success rate of indirect search is relatively high, and it will be easier to do things with people you know.

Look for it directly. It's a bit of a chance.

I don't recommend you to look online (unless you need to beat up some big sisters and aunts who do housework in the kitchen)
