Smart wrist watch

In Tianjin, 68-year-old Li Fengyun put her hand on a health check-up robot. Fifteen seconds later, she received an assessment report of her health on the cellphone.

"The health test offers me some guidance on health. It is convenient," she said.

For 61-year-old Sha Ruifang, who has a heart problem, a smart wrist watch helps monitor her physical condition, which allows her to make an outing without worrying too much about an unexpected situation.

Sha said once she was out with her family when she suddenly received a call from the smart elderly care control center, which said they had detected an irregular heartbeat through the watch and asked her if she felt unwell.

After going to hospital, Sha was diagnosed with arrhythmia. And as the problem was discovered timely, she only had to take some pills and recovered soon.
