Perhaps you should try some spelling variations:
thien van » thi van
cua triet » cua viet, su triet, va triet
van pham » san pham, van phan, van phat
duc manh » suc manh, duc anh, duc minh
nang xa » nang x, lang xa, nang ma
hanh di » hanh vi, hanh de, hang di
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
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: tu sac ky nang xa hoi. thien van pham ((duc tan) OR (duc manh)) hanh di cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. thien van pham ((duc tan) or (duc manh)) hanh di cua triet*.
