Perhaps you should try some spelling variations:
va triet » va thiet, va trien, ve triet
va hanh » van hanh, va thanh, va danh
ve cham » va cham, ve chat, vu cham
tu cach » tu cac
nang xa » nang x, lang xa, nang ma
tu nang » tru nang, tu nong, tu nano
su cac » tu cac, su cao, su can
tuc va » thuc va, truc va, tuc xa
ve cam » ve cac, va cam, ve cai
vi va » vi van, vai va, vu va

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

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