Perhaps you should try some spelling variations:
thanh hai » thanh phan, thanh san
thanh hoa » thanh pho
cua tre » cua te, cuu tre, cua triet
duc ban » duc tan, duc van, dua ban
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
ve cam » ve cham, va cam, ve cai
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 ((ve cam) OR (ve cac)) duc ban ((thanh hai) or (thanh hoa)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ((ve cam) OR (ve cac)) duc ban ((thanh hai) OR (thanh hoa)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ((ve cam) OR (ve cac)) duc ban ((thanh hai) or (thanh hoa)) cua tre*".
