Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
thanh vi » hanh vi, thanh va, thanh ve
nang xa » nang x, lang xa, nang ma
cua tre » cuu tre, cua triet, dua tren
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
ke cau » ket cau
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: te sac ky nang xa hoi. hieu ((ve cac) or (ke cau)) duc va thanh vi ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. hieu ((ve cac) OR (ke cau)) duc va thanh vi ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu ((ve cac) or (ke cau)) duc va thanh vi ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu ((ve cac) or (ke cau)) duc va thanh vi ((cua tre) OR (cua te))*.
