Perhaps you should try some spelling variations:
hanh sai » hanh san, hanh tai, danh sai
ve triet » va trien, su triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va
va hanh » van hanh, va thanh, va danh
cua duc » cua tuc, cua nuoc, cua quoc
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, luc va

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 ky lang xa hoi. ((hieu va) OR (hieu qua)) cam xuc va hanh sai ((ve triet) OR (cua duc))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang xa hoi. ((hieu va) OR (hieu qua)) cam xuc va hanh sai ((ve triet) or (cua duc))~".
• Adding a wildcard symbol may retrieve word variants: te sac ky lang xa hoi. ((hieu va) OR (hieu qua)) cam xuc va hanh sai ((ve triet) or (cua duc))*.
