Perhaps you should try some spelling variations:
vinh cuu » dinh cuu, sinh cua, dinh cu
nang xa » nang x, lang xa, nang ma
qua cam » qua cham, qua ca, qua cai
qua cac » cua cac
va hanh » van hanh, va thanh, va danh
su xac » pu xac, su cac
xac ky » cac ky, sac ky, bac ky
tuc va » thuc va, truc va, tuc xa
vi cuu » vi luu

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

• Performing a fuzzy search may retrieve terms with similar spellings: su xac ky nang xa hoi. hieu ((qua cam) or (qua cac)) tuc va hanh ((vi cuu) OR (vinh cuu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky nang xa hoi. hieu ((qua cam) OR (qua cac)) tuc va hanh ((vi cuu) OR (vinh cuu)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky nang xa hoi. hieu ((qua cam) or (qua cac)) tuc va hanh ((vi cuu) OR (vinh cuu)) tre*".
