Perhaps you should try some spelling variations:
china lan » china land, chia lan, china latin
china law » china laws
lang tan » liang tan, lang lang, tang tang
yang jui » yang judy, yang di
tan tan » tas tan, tin tan, tang tang
yang yi » yang di
yang xi » yang di
sar » sara, star, saur

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: lang tan tan ((china lan) OR (china law)) ((((yang yi) OR (yang jui))) OR (yang xi)) kong sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang tan tan ((china lan) OR (china law)) ((((yang yi) or (yang jui))) or (yang xi)) kong sar ;~".
• Adding a wildcard symbol may retrieve word variants: lang tan tan ((china lan) OR (china law)) ((((yang yi) or (yang jui))) or (yang xi)) kong sar ;*.
