Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
kho tang » cao tang
cua tre » cua te, cuu tre, dua tren
minh di » minh ai, minh de, minh duc
xa minh » xa sinh, xa tinh, xa vinh
cam tuc » cam xuc, cam tu, nam thuc
hieu va » lieu va, hieu qua
ky tang » ky nang, ky dang, ky trong
ma hoi » mai hoi, xa hoi, ma hoa
va cam » va cham, va cac, va cao
vu sai » vu hai, vu san, vu dai

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: vu sai ((ky tang) OR (kho tang)) ma hoi. hieu va cam tuc xa minh di ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai ((ky tang) or (kho tang)) ma hoi. hieu va cam tuc xa minh di ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: vu sai ((ky tang) or (kho tang)) ma hoi. hieu va cam tuc xa minh di ((cua tre) OR (cua triet))*.
