Perhaps you should try some spelling variations:
sites west » notes west, site test, sites east
yang jin » yang jun, shang jin, wang jing
yang jie » yang di, yang jui, yang xi
ying jin » jing ji
hong hai » shang hai, zhong tai, dang hai
2 sites » _ sites, et sites
dong » doing, long, done

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong sin) or (wang yan)) 2 sites west ((((yang jin) OR (yang jie))) or (ying jin)) hong hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sin) OR (wang yan)) 2 sites west ((((yang jin) OR (yang jie))) OR (ying jin)) hong hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (wang yan)) 2 sites west ((((yang jin) OR (yang jie))) or (ying jin)) hong hai ;*".
