Perhaps you should try some spelling variations:
so nganh » so ngan, hoc nganh, moi nganh
hieu van » hieu va, thien van, lieu va
cau treo » cau theo, cau triet, cau trieu
nganh ma » nganh mac, nganh hoa, nganh y
cau tren » cu tren, dau tren, ca tren
van cac » van hac, van cau, van bac
va hanh » van hanh, va thanh, ban hanh
nang xa » nang x, lang xa, nang ma
va danh » va dinh, va dan, dia danh
ma nang » may nang, mia nang, da nang

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 nganh ma nang xa hoi. hieu van cac du ((va hanh) OR (va danh)) vi ((cau treo) OR (cau tren))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so nganh ma nang xa hoi. hieu van cac du ((va hanh) or (va danh)) vi ((cau treo) OR (cau tren))~".
• Adding a wildcard symbol may retrieve word variants: so nganh ma nang xa hoi. hieu van cac du ((va hanh) or (va danh)) vi ((cau treo) OR (cau tren))*.
