Perhaps you should try some spelling variations:
trung va » truong va, trang va, trung ha
su triet » su viet, su tien, ve triet
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van dam
van cau » van dau, van hau, van chat
truc va » thuc va, thuc vat
han tai » hang tai, nhan tai, van tai
ve van » le van
tai su » tai so, tai tu, lai su

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

• Performing a fuzzy search may retrieve terms with similar spellings: ve van ky nang xa hoi. hieu ((van cam) or (van cau)) ((truc va) OR (trung va)) han tai su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ve van ky nang xa hoi. hieu ((van cam) OR (van cau)) ((truc va) OR (trung va)) han tai su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ve van ky nang xa hoi. hieu ((van cam) or (van cau)) ((truc va) OR (trung va)) han tai su triet".
• Adding a wildcard symbol may retrieve word variants: ve van ky nang xa hoi. hieu ((van cam) or (van cau)) ((truc va) OR (trung va)) han tai su triet*.
