Perhaps you should try some spelling variations:
tong song » hong song, song seng, tong king
zhang yan » zhang fan, zhang jian, wang yan
lang yan » wang yan, wang yang, yang yang
yang all » wang all, yang dali, yang li
tong sin » dong sin, tong king, gong si
est ton » est donc
ton hui » tong hui, tong shui, gong hui

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 yan) OR (zhang yan)) ((yang di) OR (yang all)) est ton hui ((tong sin) OR (tong song)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yan) OR (zhang yan)) ((yang di) or (yang all)) est ton hui ((tong sin) or (tong song)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang yan) OR (zhang yan)) ((yang di) or (yang all)) est ton hui ((tong sin) or (tong song)) ;*.
