Perhaps you should try some spelling variations:
thanh lap » thanh san, phan lap, thanh hai
hanh lai » hanh lam, hanh tai, thanh loi
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
tang ma » mang may, tang van
hieu ve » hieu va, hieu van
cao duc » dao duc, cao suc, giao duc
cac tu » cac thu, cach tu, cac du
ve cao » va cao, ve bao, ve cac

You may be able to get more results by adjusting your search query.

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