Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham
va hanh » van hanh, va thanh, va danh
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ve cam » ve cac, va cam, ve cai
tuc va » thuc va, truc va, tuc xa
vi cua » vai cua
di cua » dai cua, doi cua, de cua

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

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