《围城》以外国导演阿布的视角展示了新冠肺炎疫情期间无法回国、滞留武汉的由外国留学生组建的洋雷锋志愿队、秘鲁Sdenka Zobeida教授、巴勒斯坦瓦阿里博士、日本福冈人岛田孝治对武汉做出的贡献。疫情爆发时大量外国人撤侨回国，但他们毅然选择留在武汉，守住这座“空城”，或做志愿服务、或关注并发布疫情最新消息、或鼓励身边人保持积极乐观的心态，他们都通过自己的一份力量与武汉人民共同对抗新冠病毒，最终大家迎来了武汉的全面解封！

From the perspective of foreign director ABU, "Fortress Besieged" shows the contributions made to Wuhan by Foreign Lei Feng volunteer team formed by foreign students, Professor Sdenka Zobeida from Peru, Dr. Waali from Palestine, and Takaji Shimada from Fukuoka, Japan, who were unable to return home and stranded in Wuhan during the COVID-19 epidemic. A large number of foreigners evacuate to return home in the event of the outbreak, but they had chosen to stay in Wuhan, hold on to the "empty city", or do volunteer, or pay attention to and release the latest news of the outbreak, or encourage people around to keep positive and optimistic attitude, they all do their part to fight against coronavirus with Wuhan people, finally ushered in the Wuhan comprehensive unlock!
