Doing business is difficult. Having a local representative in China is necessary to understand the complexities of communication and culture vital to doing business there. The language has many dialects and customs varying by region. The buying process dealing in China is very different from that in the US. Everything is digital. Everything is done fast. Fast is the only speed of business. If business people are nice they have no interest in doing business with you. If the argue and criticize, they have interest. When they complete a successful transaction they become very sad. The differences in culture and language are so great that to be successful doing business in China, one must employ a knowledgable local representative.
