Perhaps you should try some spelling variations:
hieu van » thien van, lieu va, hieu ve
cuu tre » cua tre, cau tren, cau treo
va kinh » qua kinh
va tinh » may tinh
nam xuc » cam xuc, nam xua, nam thuc
hieu va » lieu va, hieu qua
sac ky » cac ky, sai ky
va cuu » va cau, va chu, va huu
te sac » te sach, te cac, te san
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: te sac ky nang x hoi. ((hieu van) OR (hieu va)) nam xuc ((va kinh) OR (va tinh)) va cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang x hoi. ((hieu van) OR (hieu va)) nam xuc ((va kinh) or (va tinh)) va cuu tre~".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang x hoi. ((hieu van) OR (hieu va)) nam xuc ((va kinh) or (va tinh)) va cuu tre*.
