Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
thanh xuc » thanh xuan, thanh huy, hanh xu
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
va hanh » van hanh, va thanh, va danh
cua tre » cuu tre, cua triet, dua tren
tu sac » tu sach, tu cac, tu bac
tu san » thu san, tu ban, tu can
xuc va » duc va, tuc va, luc va
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: ((tu sac) or (tu san)) ky nang xa hoi. hieu van thanh xuc va hanh vi ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu san)) ky nang xa hoi. hieu van thanh xuc va hanh vi ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (tu san)) ky nang xa hoi. hieu van thanh xuc va hanh vi ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) or (tu san)) ky nang xa hoi. hieu van thanh xuc va hanh vi ((cua tre) OR (cua te))*.
