2, blind from the West lack of self-confidence
3, bar management decrees vary
4, the construction mechanism to be innovative
◆ sponge city three common problems:
1, water and water at the same time how to prevent clogging?
2, how to prevent leakage at the same time?
3, how to clean rain water preservation?
Ren Chong proposed a system solution
