Perhaps you should try some spelling variations:
thanh hai » thanh phan, thanh hoa, thanh san
hanh hai » nhanh hai, hang hai, hanh tai
cua tre » cua te, cuu tre, cua triet
dua ban » dia ban, cua ban, qua ban
van lam » van nam
van dam » van nam, van dao, van dau
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
su sac » su sach, su cac, su xac

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 nang xa hoi. hieu ((van dam) or (van lam)) dua ban ((hanh hai) OR (thanh hai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ((van dam) OR (van lam)) dua ban ((hanh hai) OR (thanh hai)) 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 lam)) dua ban ((hanh hai) OR (thanh hai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu ((van dam) or (van lam)) dua ban ((hanh hai) OR (thanh hai)) cua tre*.
