Perhaps you should try some spelling variations:
phuong cong » phuong dong, phong cong, phung cong
chieu sach » chinh sach, chiet tach, chieu sang
cong thanh » dong thanh, cong trinh, cong tan
va phuong » va thuong, cac phuong
ho chieu » theo chieu, hoc thieu, doi chieu
hanh han » hanh nhan, hanh phan, anh han
hanh san » thanh san, khach san, thanh son
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 chieu sach - ((hanh han) OR (hanh san)) va phuong cong thanh ((toan cao) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((hanh han) OR (hanh san)) va phuong cong thanh ((toan cao) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((hanh han) OR (hanh san)) va phuong cong thanh ((toan cao) or (van ban))*.
