Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
dong skin » dong sin, dong bin, dof skin
a cheung » _ cheung, wai cheung, a chen
a ch'ing » _ ch'ing, a caring, a chain
chan mun » chak mun, chan ming, chan jan
dong di » dong sin
mun you » man you, run you, mun young
yama » rama, yams, yam

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: ((((dong yang) OR (dong di))) OR (dong skin)) yama ((a cheung) OR (a ch'ing)) chan mun you zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong yang) or (dong di))) or (dong skin)) yama ((a cheung) OR (a ch'ing)) chan mun you zhi ;~".
• Adding a wildcard symbol may retrieve word variants: ((((dong yang) or (dong di))) or (dong skin)) yama ((a cheung) OR (a ch'ing)) chan mun you zhi ;*.
