Perhaps you should try some spelling variations:
hanh thai » nhanh thai, hinh thai, hanh tai
thai cua » than cua, tai cuc, tri cua
nang xa » nang x, lang xa, nang ma
van dam » van dao, van dau, van lam
dua ban » dia ban, cua ban, mua ban
qua ban » cua ban, qua quan
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ((van dam) OR (van nam)) ((dua ban) OR (qua ban)) hanh thai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ((van dam) or (van nam)) ((dua ban) OR (qua ban)) hanh thai cua tre~".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu ((van dam) or (van nam)) ((dua ban) OR (qua ban)) hanh thai cua tre*.
