Perhaps you should try some spelling variations:
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
va hanh » van hanh, va thanh, va danh
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cao » va cao, ve bao, ve cac
va bao » va bai

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 lang xa hoi. hieu ((ve cao) or (va bao)) duc va hanh vi ((cuu tre) OR (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang xa hoi. hieu ((ve cao) OR (va bao)) duc va hanh vi ((cuu tre) OR (cua tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu ((ve cao) or (va bao)) duc va hanh vi ((cuu tre) OR (cua tre))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu ((ve cao) or (va bao)) duc va hanh vi ((cuu tre) OR (cua tre))*.
