Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thu sac » thu sach, thu san, thu xac
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
hanh di » hanh vi, hanh de, hang di
sac ky » cac ky, sai ky
va cau » van cau, va cac, va dau
xuc va » tuc va, luc va, xac va
di cua » dai cua, doi cua, de 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: thu sac ky nang xa hoi. hieu va cau ((xuc va) OR (duc va)) hanh di cua triet~.
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang xa hoi. hieu va cau ((xuc va) or (duc va)) hanh di cua triet*.
