Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
trinh khai » trinh kham, trinh tai, trinh thi
tranh cua » manh cua
doanh cua » doanh luan
trinh han » trinh quan
ho chieu » theo chieu, hoc thieu, doi chieu

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 xanh - canh ((tranh cua) OR (doanh cua)) nhung cong ((trinh khai) OR (trinh han)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - canh ((tranh cua) or (doanh cua)) nhung cong ((trinh khai) OR (trinh han)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - canh ((tranh cua) or (doanh cua)) nhung cong ((trinh khai) OR (trinh han)) cau*.
