Perhaps you should try some spelling variations:
danh vai » danh sai, danh va, doanh van
cuu tre » cau tren, cau treo
ky lang » ky nang, ky dang, tay lang
cua tre » cua te, cua triet, dua tren
ky tang » ky nang, ky dang, kho tang
hieu va » lieu va, hieu qua
cam duc » cam xuc, cao duc, pham duc
va danh » va dinh, va dan, va hanh
tu sac » tu sach, tu cac, tu san
va cam » va cham, va cac, va cao

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 lang) OR (ky tang)) xa hoi. hieu va cam duc va danh vai ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky lang) OR (ky tang)) xa hoi. hieu va cam duc va danh vai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky lang) OR (ky tang)) xa hoi. hieu va cam duc va danh vai ((cua tre) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky lang) OR (ky tang)) xa hoi. hieu va cam duc va danh vai ((cua tre) or (cuu tre))*.
