Perhaps you should try some spelling variations:
liang dan » liang tan, king dan, liang sun
dong yang » dong hoang, wang yang, yang yang
chan chen » chang chen, chan hei, chan chak
chen ping » chen rong, chen yang, chen wang
ping shih » ming shih
bei chan » bei celan, bei hans
dong di » dong sin
et a » et al, et la, e a
ye a » yet a, e a, me a

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: ((liang dan) OR (((dong yang) OR (dong di)))) ((et a) OR (ye a)) bei chan chen ping shih ;~.
• Adding a wildcard symbol may retrieve word variants: ((liang dan) or (((dong yang) or (dong di)))) ((et a) or (ye a)) bei chan chen ping shih ;*.
