In one of its own documents, the China Media Group (中央广播电视总台), also known as Voice of China, stated that, on January 1, 2020, it released an internal reference report (内参) to the higher ups regarding the coronavirus in Wuhan.
Staff from its Wuhan station conducted research on the issue on December 31 and created two reports, including data, analysis, and recommendations, and circulated them to the higher ups on January 1. It didn’t mention who was included in its circulation, but normally it should have reached the top Chinese Communist Party (CCP) leaders and the Central government.
Excerpt in Chinese:
2019年12月30日深夜，一场疫情防控阻击战在武汉揭开序幕。在这重大时刻，以共产党员为骨干的总台央广湖北记者站七位同志责无旁贷毅然决然投身到疫情最严重的第一线，开始了一个多月的持续奋战。
2019年12月31日，疫情信息一出现，站长王志刚当即布置了内参报送任务，要求全站记者把工作注意力向疫情防控转移，发现情况及时预警。接着，迅速建立针对性的疫情报道工作机制，确保高效运转。在记者站的统一安排下，大家分头行动，广泛深入医院、社区、学校，开始了一场抗击疫情零距离“肉搏战”。
副站长张毛清来到与华南海鲜市场相邻的汉口火车站，了解车站人流和防控压力，并向出租车司机了解社会反映。记者左艾甫采访武汉市华南海鲜市场经营户和附近居民，了解海鲜市场卫生面貌。当天记者站就采制了两篇有数据、有分析、有建议的重要内参。2020年元旦，左艾甫没有休息再次来到专门收治重症肺炎病人的金银潭医院采访患者家属，当天编发了建议对不明原因肺炎患者实行免费治疗的内参。
