Perhaps you should try some spelling variations:
gianh lai » gian lan
nam thuoc » nam thuc, nam thu, nha thuoc
va gianh » va gian, van giang, va giai
sang mai » sang ma, sang tai, lang mai
cua tre » cua te, cuu tre, cua triet
lai cua » dai cua, hai cua, lai chau
hieu ve » hieu va, hieu van
mai hoi » mai khoi, dai hoi, lai hoi
ky sang » ky nang, ky dang, ky tang
te sach » toc sach
te sac » te cac, te san

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te sach)) ky sang mai hoi. hieu ve ((nam thuoc) OR (cam xuc)) va gianh lai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) OR (te sach)) ky sang mai hoi. hieu ve ((nam thuoc) or (cam xuc)) va gianh lai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sac) OR (te sach)) ky sang mai hoi. hieu ve ((nam thuoc) or (cam xuc)) va gianh lai cua tre*.
