Perhaps you should try some spelling variations:
va danh » va hanh, dia danh, va thanh
va dinh » van dinh, va kinh, va tinh
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
lai cua » dai cua, hai cua, lai chau
cam luc » cam xuc, cau luc
va dan » ca dan, va dao, va dau
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
cua te » cua tu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang xa hoi. hieu va cam luc ((((va danh) OR (va dinh))) or (va dan)) lai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. hieu va cam luc ((((va danh) OR (va dinh))) OR (va dan)) lai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu va cam luc ((((va danh) OR (va dinh))) or (va dan)) lai cua te".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu va cam luc ((((va danh) OR (va dinh))) or (va dan)) lai cua te*.
