Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
thai va » thai van
xuc va » duc va, tuc va, luc va
va han » va phan, van han, va hanh
tai va » tri va, dai va, tai ba
x hoi » xa hoi, o hoi, x ho
thiet » thieu

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 nang x hoi. hieu ve cham xuc va han ((((tai va) OR (mai va))) or (thai va)) thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang x hoi. hieu ve cham xuc va han ((((tai va) OR (mai va))) OR (thai va)) thiet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang x hoi. hieu ve cham xuc va han ((((tai va) OR (mai va))) or (thai va)) thiet".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang x hoi. hieu ve cham xuc va han ((((tai va) OR (mai va))) or (thai va)) thiet*.
