I want to take my son and daughter to live in Kaili for a while in the summer vacation. My son is three years old and my daughter just turned five months old. How many clothes do I need to bring? I'll take them both alone ... Compared with my hometown, the climate here is still relatively cool, and I can't live without quilts at night. It is hot at noon, rainy and humid. You'd better prepare sunscreen or something when you go out. People here generally speak some local Mandarin that you can understand.
