Perhaps you should try some spelling variations:
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
qua cam » qua cham, qua cac, qua ca
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
vai cua » dai cua, hai cua, lai cua
su can » su van, su cao, tu can
can ky » van ky, dan ky, ban ky
cua su » qua su

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: su can ky ((nang xa) OR (lang xa)) hoi. hieu qua cam xuc ((va hanh) OR (va danh)) vai cua su~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su can ky ((nang xa) OR (lang xa)) hoi. hieu qua cam xuc ((va hanh) or (va danh)) vai cua su~".
• Adding a wildcard symbol may retrieve word variants: su can ky ((nang xa) OR (lang xa)) hoi. hieu qua cam xuc ((va hanh) or (va danh)) vai cua su*.
