Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
chiet tach » chieu sach
phuong dan » phuong danh, phuong doan, huong dan
trung cap » truong cao, trung tam
ho chiet » ho chieu, ho thiet, hoc thiet
manh cua » doanh cua, ban cua
toan cau » toan ban, toan tap, toan tai
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: ho chiet tach - hanh ((manh cua) OR (trung cap)) nhung phuong dan ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - hanh ((manh cua) or (trung cap)) nhung phuong dan ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - hanh ((manh cua) or (trung cap)) nhung phuong dan ((toan cau) OR (toan cao))*.
