Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
ban thanh » ban hanh, ban hang
nam duoc » nam thuoc, dat duoc, nam moc
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu ve » hieu va, hieu van
da duoc » tao duoc, hoa duoc
cua tre » cua te, cuu tre, cua triet
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky tang xa hoi. hieu ve ((((nam duoc) OR (da duoc))) or (cam xuc)) ban thanh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky tang xa hoi. hieu ve ((((nam duoc) OR (da duoc))) OR (cam xuc)) ban thanh dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky tang xa hoi. hieu ve ((((nam duoc) OR (da duoc))) or (cam xuc)) ban thanh dai cua tre".
• Adding a wildcard symbol may retrieve word variants: su sac ky tang xa hoi. hieu ve ((((nam duoc) OR (da duoc))) or (cam xuc)) ban thanh dai cua tre*.
