Perhaps you should try some spelling variations:
lang yanling » wang yanling, wang yangming, zhang yunling
wuhan china » tuan china, yunnan china
than china » tuan china, han china, can china
dan yang » daun yang, tan yang, wang yang
hong hai » shang hai, zhong tai, dang hai
yang xi » yang di, yang yi, yang jui
xi hong » xie hong, kia hong, thi hong

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yanling ((than china) OR (wuhan china)) dan yang xi hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: lang yanling ((than china) OR (wuhan china)) dan yang xi hong hai ;*.
