Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
cam thuc » am thuc, nam thuc, can thuc
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cam thu » nam thu, cac thu, ca thu
va hanh » van hanh, va thanh, va danh
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
vi cua » vai cua, di cua

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 xa hoi. hieu ve ((cam thuc) OR (cam thu)) va hanh vi cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ve ((cam thuc) or (cam thu)) va hanh vi cua triet*.
