Perhaps you should try some spelling variations:
nganh khoa » nganh hoa, nganh khong, doanh khoa
hoc nganh » hoc nhanh
thu sinh » thu minh, thu kinh, thuoc sinh
cuu cong » cua cong, cac cong
khoa hoc » hoa hoc
tan tuan » tran tuan, than tuan, van tuan
tuan san » luan san, tan san, thanh san
hoc xua » hoc cua, hoc xa, hoc lua
xua hai » qua hai, cua hai, xa hai
hai tan » hai van, hai quan

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: "thu sinh hoc tap, nghien ((cuu cong) OR (thu cong)) hoc nganh khoa hoc xua hai tan tuan san~".
• Adding a wildcard symbol may retrieve word variants: thu sinh hoc tap, nghien ((cuu cong) OR (thu cong)) hoc nganh khoa hoc xua hai tan tuan san*.
