Perhaps you should try some spelling variations:
thien van » thi van
van pham » san pham, van phan, van phat
duc manh » suc manh, duc anh, duc minh
su triet » su viet, su tien, ve triet
nang xa » nang x, lang xa, nang ma
hanh de » hanh ve, hanh kem
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
de su » den su, ve su, de tu

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 de su triet~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. thien van pham ((duc tan) or (duc manh)) hanh de su triet*.
