Five sketches, five true portraits of the front line of epidemic prevention and control, and five touching moments containing infinite positive energy. These are five true stories that have made Zhang Yuan, the protagonist of the painting, restless and deeply touched in recent days. Zhang Yuan is an art teacher of Jingwei primary school in European New Town, Daoli District, Harbin. She is good at watercolor painting and traditional Chinese painting. During online teaching, in addition to normal lesson preparation and extracurricular activities, she often picked up the brush in her hand to write and draw. Recently, when performing nucleic acid testing, she not only lined up early and carefully cooperated with the testing, but also carefully observed the busy figure of community workers, medical workers and volunteers through the window. "As a teacher, I wanted to contribute to the fight against the epidemic in my own way, so I came up with the idea of recording the touching moments of nucleic acid detection with a paintbrush, so as to pay tribute to all the staff working on the front line," Zhang Yuan said. Recently, Zhang Yuan conceived and created five sketches in two days, showing the scenes of sinking cadres, community cadres, volunteers, Communists and medical workers sticking to the front line of anti epidemic and seriously doing nucleic acid for residents. In the painting, community medical staff wear protective clothing, volunteers wear red sleeve labels, sinking cadres hang badges, Party members stick labels... These details are reflected. In one picture, medical workers in protective clothing are kneeling on the ground to collect nucleic acid for residents. This painting tells that Ligong village, Taiping town goes deep into the elderly apartment in the village to collect nucleic acid for the elderly who are unable to move. Because the elderly are old and their consciousness is not very clear, the medical staff can only sample on their knees for the convenience of detection. It is understood that during the epidemic prevention and control period, the majority of Party members, cadres and workers, public security, law enforcement, volunteers and cadres in Daoli District were not afraid of risks, actively engaged in the anti epidemic war and silently dedicated their strength.
