Perhaps you should try some spelling variations:
yan chuan » say chuan, hai chuan, ka chuan
wang nan » wang yan, wang ban, wang dan
dan yang » daun yang, wang yang, yang yang
tan yang » tan ying, tan yong, tao yang
jin hong » tin hong, jin song, min hong
hong hai » shang hai, zhong tai, dang hai
nan yan » nan ya, wang yan, qian yan

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 nan yan chuan ((dan yang) OR (tan yang)) jin hong hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang nan yan chuan ((dan yang) or (tan yang)) jin hong hai ;*.
