Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nam thuc » nam thuoc, am thuc, nam thu
thuc day » thuc dan, thuc vat
nang xa » nang x, lang xa, nang ma
thi ban » thi lan, tai ban, tri ban
ban nam » van nam, dan nam, ban ham
hanh di » hanh de, hang di, danh di
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
thiet » thieu

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 ky nang xa hoi. thi ban nam thuc day ((hanh di) OR (hanh vi)) ((cua triet) or (va thiet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. thi ban nam thuc day ((hanh di) OR (hanh vi)) ((cua triet) OR (va thiet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. thi ban nam thuc day ((hanh di) OR (hanh vi)) ((cua triet) or (va thiet))*".
