Perhaps you should try some spelling variations:
nganh cong » nhanh chong, thanh cong
hoc nganh » hoc nhanh
cong hoc » dong hoc, cong hoa, cong coc
van nhan » van phan, van thanh, danh nhan
nhan dan » phan dau, gian dan, nhan tai
cac hoc » cach hoc, cac hop, bac hoc
cuu mon » cuu mo, cuu mot, cuu cong
mon hoc » toan hoc, dong hoc
lai hoi » lai hoa, lai roi, mai hoi
dai hoi » dai hoc, dai hai, dai moi

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: tu cac hoc tap, nghien cuu mon hoc nganh cong hoc ((lai hoi) OR (dai hoi)) van nhan dan~.
• Adding a wildcard symbol may retrieve word variants: tu cac hoc tap, nghien cuu mon hoc nganh cong hoc ((lai hoi) or (dai hoi)) van nhan dan*.
