Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
nang xa » nang x, lang xa, nang ma
xuc van » duc van, luc van, xuc ban
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, ve cai
va cam » va cham, va cac, va cao

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. hieu ((ve cam) or (va cam)) xuc van hanh vi ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ((ve cam) OR (va cam)) xuc van hanh vi ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ((ve cam) or (va cam)) xuc van hanh vi ((cua tre) OR (cuu tre))*".
