Perhaps you should try some spelling variations:
dang thanh » dong thanh, dang hanh, hoang thanh
thuc dang » thuoc dang, thuc dan, thuc dung
nam thuc » nam thuoc, am thuc, nam thu
nang xa » nang x, lang xa, nang ma
hieu ha » hieu hoa, hieu va, hieu ca
bai cua » ban cua, bai ca, lai cua
hai cua » thai cua, hoi cua, lai cua
su sac » su sach, su cac, su xac
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: su sac ky nang xa hoi. hieu ha nam thuc dang thanh ((((bai cua) OR (hai cua))) or (dai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ha nam thuc dang thanh ((((bai cua) OR (hai cua))) OR (dai cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ha nam thuc dang thanh ((((bai cua) OR (hai cua))) or (dai cua)) triet*".
