Perhaps you should try some spelling variations:
thanh nghia » thanh nghi, thanh nga, thanh nha
nghia cua » nghiep cua, nghia xa, nghia duy
nam thuc » nam thuoc, am thuc, nam tu
da thanh » dao thanh, dat thanh, dam thanh
hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
vu sac » vu sach, vu san, vu cac
va sac » va cac, va suc, va san
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sac) OR (va sac)) ky nang x hoi. hieu ve ((nam thuc) or (nam thu)) da thanh nghia cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sac) OR (va sac)) ky nang x hoi. hieu ve ((nam thuc) OR (nam thu)) da thanh nghia cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sac) OR (va sac)) ky nang x hoi. hieu ve ((nam thuc) or (nam thu)) da thanh nghia cua tre*".
