Perhaps you should try some spelling variations:
hanh triet » hanh thiet, hanh tiet, nganh triet
hanh tieng » anh tieng, ban tieng, hanh trang
duc manh » suc manh, duc anh, duc minh
su than » su thanh, suy than, nu than
cua tre » cua te, cuu tre, cua triet
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
va cao » va cac, va dao, va bao
va co » vo co

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

• Performing a fuzzy search may retrieve terms with similar spellings: su than ky dang xa hoi. hieu ((va cao) OR (va co)) duc manh ((hanh triet) or (hanh tieng)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su than ky dang xa hoi. hieu ((va cao) OR (va co)) duc manh ((hanh triet) OR (hanh tieng)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su than ky dang xa hoi. hieu ((va cao) OR (va co)) duc manh ((hanh triet) or (hanh tieng)) cua tre*".
