Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chieu tinh » trieu tinh, lieu tinh, chau tinh
cong manh » cong danh, duong manh, cong thanh
ho chieu » theo chieu, hoc thieu, doi chieu
tang cua » hang cua, tang luan, thong cua
mang cua » manh cua, dung cua, ban cua
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban

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 chieu tinh - hanh ((tang cua) OR (mang cua)) nhung cong manh ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - hanh ((tang cua) OR (mang cua)) nhung cong manh ((toan cau) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - hanh ((tang cua) OR (mang cua)) nhung cong manh ((toan cau) or (toan tap))*.
