Perhaps you should try some spelling variations:
xanh hanh » danh thanh, ban hanh, van hanh
xay hanh » day nhanh, day thanh, xuan hanh
sang mai » sang ma, sang tai, lang mai
nam thuc » nam thuoc, am thuc, nam thu
buu tre » cuu tre
ky sang » ky nang, ky dang, ky tang
mai hoi » mai khoi, dai hoi, lai hoi
lieu ha » lieu nha, liem ha, lieu ma
tu sac » tu sach, tu cac, tu san
sac ky » cac 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: tu sac ky sang mai hoi. ((lieu ha) OR (lieu va)) nam thuc ((xay hanh) or (xanh hanh)) tai buu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky sang mai hoi. ((lieu ha) OR (lieu va)) nam thuc ((xay hanh) OR (xanh hanh)) tai buu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky sang mai hoi. ((lieu ha) OR (lieu va)) nam thuc ((xay hanh) or (xanh hanh)) tai buu tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky sang mai hoi. ((lieu ha) OR (lieu va)) nam thuc ((xay hanh) or (xanh hanh)) tai buu tre*.
