Perhaps you should try some spelling variations:
thien van » thi van
chua tri » chua trieu, chua tivi, huu tri
nang hoc » nang doc, nang luc, dong hoc
so sanh » do sanh
sanh vu » anh vu, hanh vu, sanh va
va danh » va dinh, va dan, dia danh
va hanh » van hanh, va thanh, ban hanh
hoc xuc » hoc duc, hoa xuc, hoc nuoc
van hoc » van hoa
hoc hoi » hoc khoi, hoc hoa, hoc noi
vu nang » vuc nang, va nang, vu dang
chu tri » chu thi, chu tai, cu tri

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: so sanh vu nang hoc hoi. thien van hoc xuc ((va hanh) OR (va danh)) hai ((chua tri) OR (chu tri))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh vu nang hoc hoi. thien van hoc xuc ((va hanh) or (va danh)) hai ((chua tri) OR (chu tri))~".
• Adding a wildcard symbol may retrieve word variants: so sanh vu nang hoc hoi. thien van hoc xuc ((va hanh) or (va danh)) hai ((chua tri) OR (chu tri))*.
