Perhaps you should try some spelling variations:
nam thuoc » nam thuc, nam thu, nha thuoc
thinh bai » thanh bai, tinh bac, thong bai
cac tren » ca tren, cau tren, rac tren
hinh bai » hinh tai, hinh thai, tinh bac
tinh bai » tinh bac, tinh hai, tinh bao
thuoc xa » thuoc ma, thuoc va, thuoc la
lieu ha » lieu nha, lieu va, liem ha
nang ma » tang ma, sang ma, nang cao
sac ky » cac ky, sai ky
ma hoi » mai hoi, xa hoi, ma hoa
tu sac » tu sach, tu cac, tu 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: tu sac ky nang ma hoi. lieu ha nam thuoc xa ((hinh bai) OR (((thinh bai) OR (tinh bai)))) cac tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ma hoi. lieu ha nam thuoc xa ((hinh bai) or (((thinh bai) OR (tinh bai)))) cac tren~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ma hoi. lieu ha nam thuoc xa ((hinh bai) or (((thinh bai) OR (tinh bai)))) cac tren*.
