Perhaps you should try some spelling variations:
cam tuc » cam xuc, cam tu, nam thuc
va dinh » van dinh, va tinh, vu dinh
lam cua » nam cua, lam chat
hieu ve » hieu va, hieu van
va kinh » va tinh, qua kinh
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
cua te » cua tu
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 ve) OR (hieu qua)) cam tuc ((va dinh) OR (va kinh)) lam cua te~.
• Adding a wildcard symbol may retrieve word variants: te sac ky nang x hoi. ((hieu ve) or (hieu qua)) cam tuc ((va dinh) or (va kinh)) lam cua te*.
