Perhaps you should try some spelling variations:
gianh lai » gian lan
va gianh » va gian, van giang, va giai
sang mai » sang ma, sang tai, lang mai
dat duoc » dat nuoc, da duoc, luat duoc
cuu tre » cau tren, cau treo
mai hoi » mai khoi, dai hoi, lai hoi
hieu ve » hieu va, hieu van
cua tre » cua te, cua triet, dua tren
ky sang » ky nang, ky dang, ky tang
tai ky » thai ky, trai 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: te tai ky sang mai hoi. hieu ve ((dat duoc) or (cam xuc)) va gianh lai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te tai ky sang mai hoi. hieu ve ((dat duoc) OR (cam xuc)) va gianh lai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te tai ky sang mai hoi. hieu ve ((dat duoc) or (cam xuc)) va gianh lai ((cua tre) OR (cuu tre))*".
