An ordinary day, an extraordinary twelve hours

　　On January 29, Beijing, the whole city has entered the rhythm of the Spring Festival.

Our cameras ran for twelve hours, recording their figures—

　　At 00:00, Gaobeidian North Road, policeman Xu Rui drove a police car to patrol slowly. The blue and red police lights on the roof complemented the colorful lights on the roadside.

"Take the people's affairs as your own." He has been practicing this sentence since ten years as a police officer.

　　Ugly, at 2:03, on the winter night, railway worker Li Yuming had sweat on his forehead.

He has been fighting with the workers for more than two consecutive hours, diverting routes, grinding welds, and replacing parts. They have to complete the renovation task of the Beijing section of the Beijing-Kazakhstan railway line before 4:30 in the morning.

"The faster China's high-speed rail runs, the more stable it needs to be." He understands that he must stick to the railway line of the motherland like a railway spike.

　　Yin Shi, 3:30, on the fourth floor of the general ward building of Xuanwu Hospital of Capital Medical University, Liu Bo, a doctor of critical care medicine, walked quickly into the ward.

A patient has abnormal blood pressure that must be checked immediately.

Liu Bo kept in mind the teacher's teaching during the internship: "A good doctor should always be by the hospital bed."

　　At 5:58, at the Olympic Park, sanitation worker Lu Haijie has started a day's cleaning work.

"All of our more than 200 employees are on duty." Lu Haijie said that he was proud to serve the Winter Olympics this Spring Festival.

　　At 7:00 in the morning, Chen Jian, the driver of No. 510 Road of the Keyi Branch of Beijing Public Transport Group, was in high spirits, holding the steering wheel steadily with both hands.

The No. 510 bus he drove passed the Speed ​​Skating Stadium, Ice Cube, National Gymnasium, Bird's Nest and other venues.

"Friends who want to take pictures and punch cards during the Winter Olympics are welcome to come and ride!"

　　At 9:50, in Chaoyangmen Street, Dongcheng District, Li Hongxia, director of Beijing Zhaoyang Social Work Development Center, organized children to visit the elderly in the community.

"The more festive it is, the more lonely the empty-nesters feel." Chaoyangmen Street held a "theater for one audience" event for the elderly in difficulty in the jurisdiction. When the children visited the home to visit the elderly, they would bring a well-rehearsed performance.

　　At noon, at 11:20, Liu Haiwei from the Market Supervision Bureau of Chaoyang District, Beijing was inspecting the goods with his colleagues. As the on-site supervision staff of the Olympic special library, one of their important tasks is to ensure food safety during the Winter Olympics.

With the Winter Olympics on one side and epidemic prevention and control on the other, Liu Haiwei rarely had time to call his family.

　　未时，14:05，邮政投递员刘杰正在送件路上。春节，邮件数比平时增加了至少一半，每个投递员每天要投递近400件邮件，一直工作到夜里10点。在收件人的笑容里，刘杰感受到“这大概便是我们的价值所在吧”。

　　申时，15:15，航空总医院，前来做核酸检测的市民排成长长的队。门诊护士李跃跃埋头工作，粗略估计，她一天的检测量不少于1200人次。她曾听到市民说“看见穿白大褂的小姐姐，很有安全感”，一时热泪盈眶。前些日子，她主动报名参加核酸检测任务。她说：“家人是我坚强的后盾，而我们是患者和所有人的后盾。”

　　酉时，18:00，西城区消防救援支队府右街特勤站站长焦云龙与消防员们整装出发，驾驶消防车在辖区执勤。虽然没有接到火警任务，但他们每天24小时准备着，“守卫万家平安，是我们的职责所在”。

　　戌时，20:40，北京地铁二号线北京站，值班站长李生专注地盯着客流。每逢春节，这里客流量剧增，对李生的现场判断和指挥疏导能力是一个巨大的考验。“班组人员全员在岗。”李生说，“我不是一个人在战斗。”

　　亥时，22:50，首都国际机场，北京出入境边防检查站总站民警于海伦仍在岗位上。于海伦和他的同事们负责对广大出入境人员，特别是冬奥会相关人员的出境、入境验放工作，繁重的任务才刚刚开始。此刻，于海伦的妻子也在执勤，作为民警夫妻，他们一起在家过节的机会并不多。他们有着共同的信仰——“身着警服，不辱使命”。
