Perhaps you should try some spelling variations:
nam thuoc » nam thuc, nam thu, nha thuoc
khanh tai » thanh tai, hanh tai, nhanh thai
lieu nha » lieu khoa, lieu phap, lieu tham
thuoc xa » thuoc ma, thuoc va, thuoc la
xa khanh » xa thanh, van khanh, dat khanh
nang xa » nang x, lang xa, nang ma
lieu ha » liem ha, lieu ma, lieu da
buu tre » cuu tre
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 nang xa hoi. ((((lieu ha) OR (lieu nha))) or (lieu va)) nam thuoc xa khanh tai buu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. ((((lieu ha) OR (lieu nha))) OR (lieu va)) nam thuoc xa khanh tai buu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. ((((lieu ha) OR (lieu nha))) or (lieu va)) nam thuoc xa khanh tai buu tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. ((((lieu ha) OR (lieu nha))) or (lieu va)) nam thuoc xa khanh tai buu tre*.
