Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
sach ty » sach tu, sach thu, xach tay
va hanh » van hanh, va thanh, va danh
va cham » va chat, va tham
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
su viet » so viet
nang xa » nang x, 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach y)) ((nang xa) OR (lang xa)) hoi. hieu va cham xuc va hanh vi su viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) or (sach y)) ((nang xa) OR (lang xa)) hoi. hieu va cham xuc va hanh vi su viet~".
• Adding a wildcard symbol may retrieve word variants: su ((sach ty) or (sach y)) ((nang xa) OR (lang xa)) hoi. hieu va cham xuc va hanh vi su viet*.
