Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
ban thanh » ban hanh, ban hang
thanh vai » thanh hai, thanh van, thanh tai
hieu van » hieu va, thien van, lieu va
van lam » van nam
ky lang » ky nang, ky tang, tay lang
ky dang » ky nang, ky danh
lam xuc » cam xuc, lam duoc
xuc ban » duc ban, cuc ban, quoc ban
su bac » xu bac, du bac, su cac
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: su bac ((ky lang) OR (ky dang)) xa hoi. hieu van lam xuc ban thanh vai ((cua triet) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su bac ((ky lang) OR (ky dang)) xa hoi. hieu van lam xuc ban thanh vai ((cua triet) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su bac ((ky lang) OR (ky dang)) xa hoi. hieu van lam xuc ban thanh vai ((cua triet) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: su bac ((ky lang) OR (ky dang)) xa hoi. hieu van lam xuc ban thanh vai ((cua triet) or (cua te))*.
