Perhaps you should try some spelling variations:
hoc nhanh » hoc phan
tinh hoc » sinh hoc, tin hoc, hinh hoc
nong hoc » dong hoc, nang hoc, nong thon
te tinh » tue tinh, tre tinh, ve tinh
nhan va » nhan tai, nhan dan, nhan tao
ma hoi » mai hoi, xa hoi, ma hoa
hoi ca » hoi cua, hoi cac, hoi cau

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: "te tinh hoc tap, nghien cuu mo ((hoc nganh) OR (hoc nhanh)) nong hoc ma hoi ca nhan va~".
• Adding a wildcard symbol may retrieve word variants: te tinh hoc tap, nghien cuu mo ((hoc nganh) OR (hoc nhanh)) nong hoc ma hoi ca nhan va*.
