Hi, Polokus, if you are interested in obtaining an inexpensive copy of The Inheritors that can be shipped to China, you could try AbeBooks.com.
http://www.abebooks.com
AbeBooks is a website that allows you to search the inventory of new and used booksellers from several different countries. I just checked for The Inheritors and found 79 copies of it ranging in price from $3.64 to $199.99. (US Dollars) Although the shipping fee is usually listed for within the US or UK, you can change it to another country.
Most booksellers on AbeBooks will ship to other countries. You could first contact the stores you are interested in by email to see if they can write your address in both Chinese characters and the English alphabet. (Although it may not be likely, perhaps there might be a store employee who knows Chinese--especially if the store is located in a city like San Francisco or New York City that boast a large Chinatown.)
Another website to try is Fetchbooks at:
http://www.fetchbooks.info
They are a website I use often that searches the book inventories of many other websites, both retail websites (such Amazon and Barnes & Noble) and other book sites (including AbeBooks and even ebay sellers). They list their results in terms of price, from low to high.
Good luck to you!
