Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yan guan » gan guan, yan yuan, yang guang
chia tan » chen tan
chia lan » china land, china law, chun lan
chia wen » china won, ching wen, asia wen
hong hai » zhong tai, dang hai, hong tan
wang » wing, wan, lang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan guan ((((chia tan) OR (chia lan))) OR (chia wen)) yong kim ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan guan ((((chia tan) OR (chia lan))) or (chia wen)) yong kim ((hong hai) or (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan guan ((((chia tan) OR (chia lan))) or (chia wen)) yong kim ((hong hai) or (shang hai)) ;*.
