Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
dua tren » dung tren
va thanh » gia thanh, ban thanh, va tinh
cuu tre » cua tre, cau tren, cau treo
ky sang » ky nang, ky dang, duy sang
hieu ve » hieu va, hieu van
dai hoi » dai hoc, dai hai, dai moi
ky tang » ky nang, ky dang, kho tang
cao luc » bao luc, cao duc, cao suc
luc va » duc va, tuc va, loc va
ve cao » va cao, ve bao, ve cac

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) OR (ky tang)) dai hoi. hieu ve cao luc va thanh vai ((cuu tre) or (dua tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ((ky sang) OR (ky tang)) dai hoi. hieu ve cao luc va thanh vai ((cuu tre) OR (dua tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ((ky sang) OR (ky tang)) dai hoi. hieu ve cao luc va thanh vai ((cuu tre) or (dua tren))*".
