Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
cam duc » cam xuc, pham duc, nam duoc
tai cua » thai cua, tai cuc, tri cua
anh tai » hanh tai, anh thai, vanh tai
tan anh » tuan anh, tran anh, toan anh
cao duc » dao duc, cao suc, giao duc
hieu ve » hieu va, hieu van
su sai » su tai, su dai, su mai
su hai » su tai
x hoi » xa hoi, o hoi, x ho

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: ((su sai) OR (su hai)) ky nang x hoi. hieu ve ((cam duc) OR (cao duc)) tan anh tai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sai) OR (su hai)) ky nang x hoi. hieu ve ((cam duc) or (cao duc)) tan anh tai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((su sai) OR (su hai)) ky nang x hoi. hieu ve ((cam duc) or (cao duc)) tan anh tai cua tre*.
