Perhaps you should try some spelling variations:
nganh nong » nganh cong
hoc nganh » hoc nhanh
nong hoc » dong hoc, nang hoc, nong thon
nhan dan » phan dau, gian dan, nhan tai
cuu mon » cuu mo, cuu mot, cuu cong
mon hoc » toan hoc, dong hoc
va nhan » van nhan, ca nhan, va phan
hoc xa » hoc ma

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((benh hoc) OR (sinh hoc)) tap, nghien cuu mon hoc nganh nong hoc xa hoi va nhan dan~".
• Adding a wildcard symbol may retrieve word variants: tu ((benh hoc) OR (sinh hoc)) tap, nghien cuu mon hoc nganh nong hoc xa hoi va nhan dan*.
