Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thanh hai » thanh phan, thanh hoa, thanh san
nang xa » nang x, lang xa, nang ma
ve chao » ve chat, ve cham, ve chang
hai cua » thai cua, dai cua, hoi cua
cua tre » cua te, cuu tre, cua triet

can ky » van ky, dan ky, ban ky
ve cho » ve co, de cho, ke cho
ve che » va che, ke che, de che
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 can ky nang xa hoi. hieu ((ve chao) or (((ve cho) OR (ve che)))) xu ban thanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su can ky nang xa hoi. hieu ((ve chao) OR (((ve cho) OR (ve che)))) xu ban thanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su can ky nang xa hoi. hieu ((ve chao) or (((ve cho) OR (ve che)))) xu ban thanh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: su can ky nang xa hoi. hieu ((ve chao) or (((ve cho) OR (ve che)))) xu ban thanh hai cua tre*.
