Perhaps you should try some spelling variations:
thanh tai » thanh hai, thanh toan, thanh san
suc dinh » su dinh, luoc dinh, sung dinh
nang xa » nang x, lang xa, nang ma
cuu tre » cua tre, cau tren, cau treo
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ve cai » va cai, ve tai, ve cau
ve cac » va cac, vien cac

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 cai) or (ve cac)) suc dinh ((thanh tai) OR (doanh tai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ((ve cai) OR (ve cac)) suc dinh ((thanh tai) OR (doanh tai)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ((ve cai) or (ve cac)) suc dinh ((thanh tai) OR (doanh tai)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu ((ve cai) or (ve cac)) suc dinh ((thanh tai) OR (doanh tai)) cuu tre*.
