Ventilation corridors part of plan for Beijing district

Smog, heat can be channeled away by network of parks, rivers and structures

As the Beijing city government enters the final stage of its relocation to new offices in the east-side Tongzhou district, experts have proposed building "ventilation corridors" to prevent the kind of smog seen in downtown areas.

The corridors are envisioned as a network of parks, rivers, highways, bridges and low buildings, which together allow air to travel more freely.
