Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
thanh van » thanh san, thanh toan, thanh phan
thuy san » thuat san, thuy anh
hieu van » hieu va, thien van, lieu va
va thanh » gia thanh, ban thanh, va tinh
va triet » va thiet, va trien, ve triet
nang xa » nang x, lang xa, nang ma
tu sac » tu sach, tu cac, tu san
nam tu » nam thu, nam thuc

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) or (thuy san)) ky nang xa hoi. hieu van nam tu va thanh van ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (thuy san)) ky nang xa hoi. hieu van nam tu va thanh van ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (thuy san)) ky nang xa hoi. hieu van nam tu va thanh van ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) or (thuy san)) ky nang xa hoi. hieu van nam tu va thanh van ((cua triet) OR (va triet))*.
