Perhaps you should try some spelling variations:
han thai » han tai, ban thai, van thai
va thieu » va thiet, va hieu, va tieu
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
thai va » thai van
y nang » ky nang, ly nang, v nang
xuc va » tuc va, luc va
xac va » tac va, ac va, bac va

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 y nang xa hoi. hieu vu cham ((((xuc va) OR (xac va))) OR (duc va)) han thai va thieu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu vu cham ((((xuc va) OR (xac va))) or (duc va)) han thai va thieu~".
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. hieu vu cham ((((xuc va) OR (xac va))) or (duc va)) han thai va thieu*.
