Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
va thanh » gia thanh, ban thanh, va tinh
ky sang » ky nang, ky dang, ky tang
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
sang ma » tang ma, nang ma, sang tao
suc va » duc va, tuc va, luc va
ve cao » va cao, ve cac, ve co
ma hoi » mai hoi, xa hoi, ma hoa
ve bao » te bao, va bao

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky sang ma hoi. hieu ((ve cao) OR (ve bao)) suc va thanh vai ((cuu tre) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky sang ma hoi. hieu ((ve cao) OR (ve bao)) suc va thanh vai ((cuu tre) OR (cua tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky sang ma hoi. hieu ((ve cao) OR (ve bao)) suc va thanh vai ((cuu tre) or (cua tre))".
• Adding a wildcard symbol may retrieve word variants: tu cac ky sang ma hoi. hieu ((ve cao) OR (ve bao)) suc va thanh vai ((cuu tre) or (cua tre))*.
