Perhaps you should try some spelling variations:
thien van » thi van
hieu van » hieu va, lieu va
phan duc » pham duc, phan tu, phan dau
hanh lai » hanh lam, hanh tai, thanh lap
hieu ve » hieu va
va hanh » van hanh, va thanh, va danh
lai cua » dai cua, hai cua, lai chau
cua cau » cua cac, cua chu, cua cay
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
x hoi » xa hoi, o hoi, x ho

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: tu sac ky nang x hoi. ((hieu ve) OR (((hieu van) OR (thien van)))) phan duc va hanh lai cua cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang x hoi. ((hieu ve) or (((hieu van) OR (thien van)))) phan duc va hanh lai cua cau~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang x hoi. ((hieu ve) or (((hieu van) OR (thien van)))) phan duc va hanh lai cua cau*.
