Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
hanh vai » hanh vi, hanh va, hanh tai
nang xa » nang x, lang xa, nang ma
xuc van » duc van, luc van, vuc van
cua tre » cuu tre, cua triet, dua tren
tu sai » tu bai, tu san, tu cai
sai ky » sac ky
ve cam » ve cham, ve cac, ve cai
va cam » va cham, va cac, va cao
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 sai ky nang xa hoi. hieu ((ve cam) OR (va cam)) xuc van hanh vai ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky nang xa hoi. hieu ((ve cam) OR (va cam)) xuc van hanh vai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky nang xa hoi. hieu ((ve cam) OR (va cam)) xuc van hanh vai ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu sai ky nang xa hoi. hieu ((ve cam) OR (va cam)) xuc van hanh vai ((cua tre) or (cua te))*.
