Perhaps you should try some spelling variations:
thien van » thi van
cham duc » pham duc, cham soc, pham duy
van cham » van chat, van tham, va cham
su triet » su viet, su tien, ve triet
lang van » dang van, tang van, hoang van
lang xa » lang ha, dang xay
duc ban » duc tan, duc van, dua ban
hanh ve » hanh vi, hanh va
tu dang » thu dang, tu dong, su dang
dang y » dang xay
kem » kiem

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu dang y ((lang xa) or (lang van)) hoi. thien van cham duc ban ((hanh ve) OR (hanh kem)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu dang y ((lang xa) OR (lang van)) hoi. thien van cham duc ban ((hanh ve) OR (hanh kem)) su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dang y ((lang xa) or (lang van)) hoi. thien van cham duc ban ((hanh ve) OR (hanh kem)) su triet*".
