Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
su triet » su viet, su tien, ve triet
thanh vi » hanh vi, thanh va, thanh ve
cach van » cac van, canh van, cach mang
cham duc » pham duc, cham soc, pham duy
bach van » bach dan, bach dang, bach xuan
duc van » duc va, duc tan, duc manh
hieu va » lieu va, hieu qua
hieu ve » hieu van
nang xa » nang x, lang xa, nang ma
vi su » va su, ve su, ki su

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

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