Perhaps you should try some spelling variations:
hien thanh » thien thanh, hien hanh, tien thanh
cua phuong » cuu phuong, cuc phuong, luan phuong
thong tinh » thuong tinh, thong tin, thong minh
hanh manh » hanh mang, lanh manh, hoang manh
cua tong » cua cong, cua dong, cua nong
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 hien thanh - hanh manh ((cua tong) OR (cua phuong)) thong tinh toan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc hien thanh - hanh manh ((cua tong) or (cua phuong)) thong tinh toan cau*.
