Perhaps you should try some spelling variations:
minh thanh » dinh thanh, tinh thanh, hinh thanh
manh thanh » danh thanh, manh thang, anh thanh
cua tre » cua te, cuu tre, cua triet
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu ve » hieu va, hieu van
hai cua » thai cua, dai cua, hoi cua
cam duc » cao duc, pham duc, nam duoc
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 ((cam duc) or (cam xuc)) ((manh thanh) OR (minh thanh)) hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky tang xa hoi. hieu ve ((cam duc) OR (cam xuc)) ((manh thanh) OR (minh thanh)) hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky tang xa hoi. hieu ve ((cam duc) or (cam xuc)) ((manh thanh) OR (minh thanh)) hai cua tre".
• Adding a wildcard symbol may retrieve word variants: su sac ky tang xa hoi. hieu ve ((cam duc) or (cam xuc)) ((manh thanh) OR (minh thanh)) hai cua tre*.
