Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
van hanh » van thanh, ban hanh, van anh
tu sach » thu sach, su sach, te sach
vu nang » vuc nang, vu dang, v nang
va nang » van nang, da nang, cam nang
hieu va » lieu va, hieu qua
va cham » va chat, va tham
xuc van » duc van, luc van, xuc ban
vi su » ve su, ki su, oi su

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

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