I went to America on business in September. What is the weather like there? What clothes should I bring? Food? What else do you need? What should I pay attention to?

It depends on where you went in America. The consumption level in the central part of the United States is low, and the consumption level on both sides of the strait is high. If you are not familiar with American coins, you'd better use a credit card, because there are more change in the United States, and there are three kinds of coins. Sending family and friends can buy luxury goods, because American luxury goods are much cheaper than domestic ones, such as brand-name bags. Then there are drugs, vitamins and the like. Most of the medicines here are pure natural, which will be much better than those in China. There are cosmetics, chocolates and the like. You can also buy some local specialties according to where you go.
