dong thuoc » dung thuoc, dang thuoc, don thuoc
hoc nganh » hoc nhanh
sanh hoc » sinh hoc, anh hoc, danh hoc
cuu dong » cuu cong, cuu tong, cuu long

thuoc la » thuoc ma, thuoc va, thuoc tai
nhan van » nhan dan, nhan va, phan van
so sanh » do sanh

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: so sanh hoc tap, nghien cuu dong hoc nganh dong thuoc la ((hoi ca) OR (hoi cac)) nhan van~.
• Adding a wildcard symbol may retrieve word variants: so sanh hoc tap, nghien cuu dong hoc nganh dong thuoc la ((hoi ca) or (hoi cac)) nhan van*.
