Perhaps you should try some spelling variations:
thanh ban » thanh san, thanh van, thanh bac
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van cau
xuc van » luc van, vuc van, xuc ban
duc van » duc va, duc tan, duc manh
su viet » so viet
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky

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 san ky nang xa hoi. hieu van cam ((xuc van) OR (duc van)) thanh ban ((cua triet) OR (su viet))~.
• Adding a wildcard symbol may retrieve word variants: tu san ky nang xa hoi. hieu van cam ((xuc van) or (duc van)) thanh ban ((cua triet) or (su viet))*.
