Perhaps you should try some spelling variations:
zhang yan » zhang fan, zhang jian, wang yan
tong song » song seng, tong king
hong song » hong kong, hong jong, hong hong
tong sin » dong sin, tong king, gong si
yang li » yang lin, yang xi, yang yi
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: zhang yan ((yang di) OR (yang li)) est ton hui ((tong sin) OR (((tong song) OR (hong song)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yan ((yang di) or (yang li)) est ton hui ((tong sin) or (((tong song) OR (hong song)))) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang yan ((yang di) or (yang li)) est ton hui ((tong sin) or (((tong song) OR (hong song)))) ;*.
