Perhaps you should try some spelling variations:
dong thanh » truong thanh
thuc dong » thuoc dong, thuc dung, phuc dong
hieu nghe » lieu nghe, hiem ngheo, nhiem nghe
nghe nam » nghe lam, nghiep nam, nghe nano
thanh vi » hanh vi, thanh va, thanh ve
trang xa » trang va, trang ha, trong xa
nam thuc » nam thuoc, am thuc, nam thu
tang xa » tang ma, lang xa, tang ha
vu cac » va cac, tu cac, ve cac
cua tu » cua tuc, cua su, cua cu

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu cac ky ((tang xa) OR (trang xa)) hoi. hieu nghe nam thuc dong thanh vi ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu cac ky ((tang xa) OR (trang xa)) hoi. hieu nghe nam thuc dong thanh vi ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu cac ky ((tang xa) OR (trang xa)) hoi. hieu nghe nam thuc dong thanh vi ((cua te) or (cua tu))*".
