China Mall Uses Smart Glass Doors to Deter Smoking

Two shopping malls in Shenzhen, China, have installed special glass doors in their men's toilets.

These doors stay opaque normally but turn transparent if smoke is detected.

This is to stop people from smoking inside.

The idea is to make smokers visible as a deterrent.

Many people on social media like this new technology and want it to be used in more places.

However, some people are worried about privacy.

The malls say they will adjust the sensors to avoid false alarms.

In India, smoking is already banned in all public places, and there are strict rules about selling and advertising tobacco.
