Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
tranh luan » trinh luat, doanh luan, tang luan
trinh luan » trinh luat, trinh quan, trinh han
hoc chieu » hoc thieu, ho chieu, hoc hien
cong san » cong tac
san chan » san chang, dan chan, san chay
chan cao » chan cho, chat cao, chay cao

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - canh ((tranh luan) OR (trinh luan)) trong cong san chan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - canh ((tranh luan) OR (trinh luan)) trong cong san chan cao*.
