Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
cau treo » cau theo, cau tren, cau triet
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van cau
duc ban » duc tan, dua ban, duc man
cuu tre » cua tre, cau tren
duc van » duc va, duc tan, duc manh
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang xa hoi. hieu van cam ((duc ban) or (duc van)) thanh vai ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu van cam ((duc ban) OR (duc van)) thanh vai ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu van cam ((duc ban) or (duc van)) thanh vai ((cuu tre) OR (cau treo))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu van cam ((duc ban) or (duc van)) thanh vai ((cuu tre) OR (cau treo))*.
