Perhaps you should try some spelling variations:
gianh lai » gian lan
sang mai » sang ma, sang tai, lang mai
dat duoc » da duoc, luat duoc, xuat duoc
va gianh » va gian, van giang, va giai
cua tre » cua te, cuu tre, cua triet
mai hoi » mai khoi, dai hoi, lai hoi
hieu ve » hieu va, hieu van
lai cua » dai cua, hai cua, lai chau
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 (dat nuoc))) or (cam xuc)) va gianh lai cua 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 (dat nuoc))) OR (cam xuc)) va gianh lai cua 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 (dat nuoc))) or (cam xuc)) va gianh lai cua tre*".
