Perhaps you should try some spelling variations:
bach dan » bach dang, bac dan, bach van
su triet » su viet, su tien, ve triet
bach da » bach ha, bach dang, sach dao
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
xuc ban » cuc ban, quoc ban, xuat ban
duc ban » duc tan, duc van, dua ban
ve cam » ve cham, ve cac, va cam
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 da) OR (bach dan)) nang xa hoi. hieu ve cam ((xuc ban) or (duc ban)) hanh vi su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((bach da) OR (bach dan)) nang xa hoi. hieu ve cam ((xuc ban) OR (duc ban)) hanh vi su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((bach da) OR (bach dan)) nang xa hoi. hieu ve cam ((xuc ban) or (duc ban)) hanh vi su triet*".
