Perhaps you should try some spelling variations:
thuong nganh » trong nganh, thuong ngay, thuong gap
thuong manh » thuong mach, thuong mai, duong manh
trung tuan » trung thanh, trung tam, tran tuan
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
dung cua » dung luan, dung cho
toan cau » toan cao, toan ban, toan tap

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: hoc thieu xanh - hanh ((dung cua) OR (trung tuan)) hang ((thuong manh) OR (thuong nganh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh ((dung cua) or (trung tuan)) hang ((thuong manh) OR (thuong nganh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((dung cua) or (trung tuan)) hang ((thuong manh) OR (thuong nganh)) toan cau*.
