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 » cua te, cuu tre, cua triet
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cau » va cau, ve cac, ve cai
le cau » le mau, le cap
ke cau » ket cau
vi cua » vai cua, di cua

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