Can you bring a few lemons, avocados, apples just for personal use?

Hi, according to Chinese laws, the fiuits are not allowed to take into China, so you had better not do that.

it should not be any problem if it's in checked in baggage, my family visiting me here from Europe brought me all kinds of food and no problems, although bringing fruit into chine I consider as joke, all items you mentioned is no problem to buy in any supermarket or on street for low price
