Yang Wei walked into his office and put on his augmented reality patrol glasses every morning. Through a tiny screen inside this black streamlined design, the information engineer was able to immediately see the name and temperature of anyone he encountered in the company.

This device was of great help during the COVID-19 pandemic earlier this year, said Yang while connecting the glasses to his cellphone with a data cable. "We use the glasses to monitor everyone's health condition as long as the person's information is included in the company's database."

With such advanced technology in hand, Yang was not working in the bustling central business district of any metropolis. As an engineer of the 5G technology in China Construction Eighth Engineering Division in Xiong'an New Area, Hebei province, Yang spent most of his time building sites, examining 5G base stations and making sure the signals are stable and at work.
