Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thanh hai » thanh phan, thanh hoa, thanh san
cua triet » cua viet, su triet, va triet
nang xa » nang x, lang xa, nang ma
ve chao » ve chat, ve cham, ve chang
cua tre » cua te, cuu tre, dua tren
su cac » tu cac, su cao, su can
ve cho » ve co, ve che, de cho
xu ban » xuc ban, tu ban, vu ban

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

• Performing a fuzzy search may retrieve terms with similar spellings: su cac ky nang xa hoi. hieu ((ve chao) or (ve cho)) xu ban thanh hai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cac ky nang xa hoi. hieu ((ve chao) OR (ve cho)) xu ban thanh hai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac ky nang xa hoi. hieu ((ve chao) or (ve cho)) xu ban thanh hai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: su cac ky nang xa hoi. hieu ((ve chao) or (ve cho)) xu ban thanh hai ((cua tre) OR (cua triet))*.
