Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
toc sach » hoc sach, doc sach, thuoc sach
cham xuc » cam xuc, chat xuc, cham soc
va hanh » van hanh, va thanh, va danh
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
nang xa » lang xa, nang ma, mang xa
xuc va » duc va, tuc va, luc va
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: ((te sach) or (toc sach)) ky ((nang xa) OR (nang x)) hoi. hieu ve cham xuc va hanh vi su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ky ((nang xa) OR (nang x)) hoi. hieu ve cham xuc va hanh vi su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (toc sach)) ky ((nang xa) OR (nang x)) hoi. hieu ve cham xuc va hanh vi su triet*".
