One of the major challenges for tourists visiting China is the language. Most Chinese don't speak English much beyond "Hello". The Effective Language Learning Center classifies Mandarin and Cantonese as the most difficult languages for native English speakers. This means that you need not necessarily feel embarrassed about not knowing how to say something in Chinese.
You can instead use body language and hand signs. It is important to appreciate that body language in China differs a lot with the West. Body language and gestures form a vital component of the rich Chinese heritage and culture, and thus should not be overlooked when visiting China.
