Perhaps you should try some spelling variations:
lang van » dang van, hoang van, giang van
tang van » dang van, hoang van, trong van
cham luc » cham soc, nhan luc, cham cuu
hanh mai » hanh ma, hanh mau, hanh may
hieu va » lieu va, hieu qua
va cham » va chat, va tham
va hanh » van hanh, va thanh, va danh
te sac » te sach, te san
te cac » tu cac, ve cac, te cao
luc va » duc va, tuc va, loc va
thiet » thieu

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: ((te sac) OR (te cac)) ky ((lang van) OR (tang van)) hoi. hieu va cham luc va hanh mai va thiet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) OR (te cac)) ky ((lang van) or (tang van)) hoi. hieu va cham luc va hanh mai va thiet~".
• Adding a wildcard symbol may retrieve word variants: ((te sac) OR (te cac)) ky ((lang van) or (tang van)) hoi. hieu va cham luc va hanh mai va thiet*.
