There is evidence that the English name of BBQ may come from the Caribbean. Once upon a time, when French pirates came to the Caribbean, they would roast the whole slaughtered sheep from beard to bottom on the grill. This kind of food is called barbe-cul for short (the "L" at the end of French cul is silent), and later it evolved into the word barbeque, and because cue is homophonic with the English letter Q, it became Barbeque, and later it was more concise and written as BBQ.
In terms of food in China, there is a barbecue called roast flavor, including roast goose, fried chicken with soy sauce, barbecue and barbecued pork. It is not a barbecue that diners can cook immediately, but it is also called BBQ in English.
The extended meaning of bbq:
This is an interesting cooking method, a bit like kebabs in Xinjiang, China. Barbecues are usually held outdoors. When people go out, they usually put charcoal on the barbecue table, then light it with fire, then put a metal barbecue grill above the charcoal, then put raw fish, meat and other foods on the barbecue grill, and spread some seasonings such as soy sauce and Chili noodles on the food.
In western countries, barbecue is a popular cooking method when people have a picnic outdoors or go camping. Barbecues are also common at Christmas parties in Australia and New Zealand. This way is often used for family outings. In the United States, Britain and other places, college students often drive in droves to a scenic place and enjoy a "barbecue".
