Perhaps you should try some spelling variations:
hanh dinh » thanh dinh, hinh dinh, hanh tinh
van hanh » van thanh, ban hanh, van anh
dinh cua » dinh cuu, sinh cua, dinh cu
hieu ve » hieu va, hieu van
cac xuc » cac nuoc, chat xuc, cac cuoc
cua tre » cua te, cuu tre, cua triet
sac ky » sai ky
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: tu ((sac ky) or (cac ky)) nang x hoi. hieu ve ((cac xuc) OR (cam xuc)) van hanh dinh cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (cac ky)) nang x hoi. hieu ve ((cac xuc) OR (cam xuc)) van hanh dinh cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) or (cac ky)) nang x hoi. hieu ve ((cac xuc) OR (cam xuc)) van hanh dinh cua tre*".
