Geng Tian communicates with his colleague inside a laboratory via walkie-talkie at a nucleic testing base in north China's Tianjin, March 19, 2022. Geng Tian, 49, is a medical worker with Tianjin First Hospital. Amid the recent COVID-19 resurgence, Geng is in charge of managing nucleic acid samples testing at a local testing base, which has daily testing capability of over 15,000 tubes.

To ensure the smooth operation with faster speed, Geng works around the clock every day in a clean corridor with a length of 30 meters in the base. His makeshift desk is made of two paper boxes, on which he waits for new batches of samples coming in, screens samples and sometimes takes a nap for a short break.

Just like Geng, other medical workers in the base are on duty day and night, in a hope of bringing the epidemic under control and resuming residents' usual hustle and bustle soon. (Xinhua/Sun Fanyue)
