Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
cham xuc » cam xuc, chat xuc, cham soc
hanh va » hang va, hanh vi
danh va » doanh va, anh va, dan va
sach ky » sac ky, sach y, sach ty
su sach » so sach, vu sach
hieu ve » hieu va, hieu van
tang ma » tang van
ve cham » va cham, ve chat, vu cham
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((mang may) or (tang ma)) hoi. hieu ve cham xuc va ((danh va) OR (hanh va)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((mang may) OR (tang ma)) hoi. hieu ve cham xuc va ((danh va) OR (hanh va)) su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((mang may) or (tang ma)) hoi. hieu ve cham xuc va ((danh va) OR (hanh va)) su triet".
• Adding a wildcard symbol may retrieve word variants: su sach ky ((mang may) or (tang ma)) hoi. hieu ve cham xuc va ((danh va) OR (hanh va)) su triet*.
