What do you need to prepare for a business trip to Guangdong and what should you pay attention to?

Take some winter clothes, such as two coats, one or two sweaters, and the rest is almost the same. The coldest temperature in Guangdong is about 5 degrees, so it won't take long to eat, use and use medicine. You don't need to bring a bag so far. The safe thing is not to go out at night and not to be accompanied. Just try not to go to some remote places, and the rest should be fine.
