First of all, I think it depends on the taste of the landlord ~ I don't know if you like spicy food or can eat it. Sichuan cuisine is generally spicy. I think if it's convenient to bring food, you can bring some Nanxi dried tofu, which is a little bigger in packaging and has all kinds of flavors, such as spiced and pickled peppers. Last time I went to Shanghai, a friend brought her a bag. Later, she told me that everyone in the family liked it. As for great veal, I forgot whether there is any in Beijing. It seems that I saw a discount, so I don't need to buy it. Of course, if not, you can still bring some. In addition, there are cooked food, and it will be difficult to bring soup. I think children from other places prefer to eat braised beef from Chengdu, which is usually sold in some small shops specializing in cold food, but not in shopping malls. If you want to bring cooked food, you can bring some Liaoji saute spicy chicken to make chicken wings. Personally, I think it's delicious, but it's a little spicy. See if you like spicy food. Some people also asked to bring Sichuan sausage and bacon home to eat, but this is heavier and takes up space.
