Perhaps you should try some spelling variations:
hoc nganh » hoc nhanh
nang thuc » dang thuoc, nhanh thuc, trang thuc
manh hoc » anh hoc, manh ho, manh hon
nang buc » nang luc, nang phuc, rang buoc
van phan » van phong, van thanh, luan phan
tu manh » tu minh, tu hanh, vu manh
hoi van » hoi va, hoi dan, hai van
mo hoc » mon hoc, co hoc

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 manh hoc tap, nghien cuu mo hoc nganh ((nang buc) OR (nang thuc)) xa hoi van phan tu~".
• Adding a wildcard symbol may retrieve word variants: tu manh hoc tap, nghien cuu mo hoc nganh ((nang buc) OR (nang thuc)) xa hoi van phan tu*.
