One day，How long？From Zi Shi to Hai Shi，Changes between minutes and seconds，When the eternal twelve o’clock encounters the stuck duty personnel under the epidemic，Between day and night，Changes between minutes and seconds，Engraved with their busy figures...Next，Please follow a group of pictures，Experience the frontline fight against the epidemic of Sunjiacha Longhua Mining Company together。(Author: Xue Xiaocheng  Editor: Wang Yu)
