Perhaps you should try some spelling variations:
danh lai » danh sai, gianh lai, dinh lam
nam duoc » nam thuoc, da duoc, dat duoc
cuu tre » cua tre, cau tren, cau treo
ky sang » ky nang, ky dang, duy sang
lai cuu » lai cua, lai chau, lai cuoc
ky tang » ky nang, ky dang, kho tang
mai hoi » mai khoi, dai hoi, lai hoi
hieu ve » hieu va, hieu van
va danh » va dinh, va dan, va hanh
te lai » te tai, te bai

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

• Performing a fuzzy search may retrieve terms with similar spellings: te lai ((ky sang) OR (ky tang)) mai hoi. hieu ve ((nam duoc) or (cam xuc)) va danh lai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te lai ((ky sang) OR (ky tang)) mai hoi. hieu ve ((nam duoc) OR (cam xuc)) va danh lai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te lai ((ky sang) OR (ky tang)) mai hoi. hieu ve ((nam duoc) or (cam xuc)) va danh lai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te lai ((ky sang) OR (ky tang)) mai hoi. hieu ve ((nam duoc) or (cam xuc)) va danh lai cuu tre*.
