Let's look at a few statistics first:

•  Over 3.380 million Chinese people have access to the Internet (reporting date; July, 2009). 
•  Web users are four times more likely to purchase from a site that communicates in the customer's language (www.idc.com).
•  Visitors stay for twice as long (Site stickiness is doubled), if a website is in their own language (Forrester Research). 

China is a huge market that is too significant to be ignored. Do you have the plan to enter this great market? If your answer is YES, the second question is coming up. How can you open the door of this market? Language barrier is a problem that you must consider. With a website presented in English on the Internet, you have little chance to expend your business to China. So you need a website in Chinese version.
