年底假期本来没打算回国，虽然国内从11月底开始逐步放松了疫情防控力度，也不断有家人和朋友感染新冠的，但是大家都可以在家里隔离，当时还没有听说任何重症，唯一着急上火的是买不到发烧止痛和其它疫情相关的药品设备和测试盒，还有黄桃罐头。

Chinese government relaxed the zero-COVID policy from the end of November of 2022. Subsequently, more and more COVID-19 infections occurred. At the beginning, most of the infected people were office workers. Then, more and more old people were infected. The speed of infection was extremely shocking.

感觉2022世界杯伴随了这次国内疫情防控的逐步放松，直到疫情高峰的到来。当大家还在评论卡塔尔世界杯比赛现场有几万名观众不戴口罩狂欢时，奥密克戎病毒多个变种凶残地席卷了祖国大地。其误导了专家、欺骗了众人，未感染和无症状从大多数变成了凤毛麟角，同时有症状的大多数人的表现又各有不同，好像专挑每个人的弱点下手，同时偶尔又对一些没打疫苗又长期体弱的人们展现了少有的宽容。总之，基本是没有什么规律可循，唯一可以确定的是，有基础病的老人是高危人群，容易出现重症。

The relaxation of the control of COVID-19 in China and the rapid spread of the first wave of the epidemic to the whole country almost coincided with the month when the 2022 World Cup was held. There are many fans at home. They have watched live broadcast of every late night or early morning game, and they have also been infected with COVID-19 during this time. At first, people were still questioning why tens of thousands of audience who watched the game in Qatar did not wear masks. Later, people who asked questions all fell infected, and they might get the answers by themselves.

在家人还有心情讨论世界杯比赛的时候，重症和转阴后的”后遗症“离家里的老人越来越近。世界杯的比赛直播几乎都是北京时间晚上11点和凌晨3点，球迷们大多不愿放弃这难得的时刻，熬夜在所难免，即使我们一直在提醒，疫情期间，免疫力非常重要。精彩的决赛结束了，家里的老同志们也中招躺平了。发烧咳嗽、连续数日剧烈呕吐，反应犹如过了鬼门关，后期的疲乏无力整日昏睡，更让大家忧心忡忡。我们去年2月份感染过新冠，3-6个月的免疫力已过期。在他们阳性的时候回去，我们可能到了家就得倒下，再加上入境隔离政策还没取消，就一直犹豫着没有回去。（这次在北京感染高峰期来回九天没有再被感染，一定程度上说明了阳康后十个月内仍有防止再感染的能力）。

年底放假后，我们先去了冲绳，觉得至少离国内近一些，后来才发现根本没有从冲绳出发直航回京的航班。冲绳海边还是很美的，只是我们无心欣赏，一直在关注国内家人们的情况。又有其他老同志不吃不喝病情严重的，年轻些的同志们虽然都转阴了，但是咳嗽或疲劳不止，感觉比我们得新冠后要严重得多。虽然1月8日以后入境不再隔离，但是我们归心似箭，希望在家人们最需要的时候能帮上点忙。这时得知A群友的一位前同事最近回国，通过社区和隔离点沟通后，只隔离了1天，就回家隔离了。我们马上联系了社区，社区同志提供了”居家隔离情况评估表“样本，但是要隔离点发给他们。看到了希望，我们马上订机票，直飞航班极少，几经周折和变化，最后拿到了12月31日从东京直飞天津的机票。

Afterwards, most of my family and friends believed that the epidemic was irregular, and that the virus was too cruel and cunning. Whether you have been vaccinated or not, you are likely to be infected. People with strong immunity may have severe symptoms after infection, and those who are too weak to be vaccinated may recover quickly after infection. The only common point that can be drawn is that many elderly people with basic diseases are easy to become severe patients after being infected.

More and more old people at home are infected with COVID-19. Some symptoms are very serious and last for a long time. There is also an old man who has been rescuing in the emergency room. Although there is no need to be isolated when we return home after January 8, we are eager to return home right now, stay with them and take care of them. After numerous setbacks, we finally returned to Tianjin, China on December 31, 2022, and arrived in Beijing on January 1, 2023 to meet our family. On January 8, 2023, when China lifted its entry quarantine, we embarked on the journey of returning to Japan.

12月29日下午我们提前回到东京并去中国驻日本大使馆指定的机构测了核酸（每人大概1,500多元人民币，国内相同的测试费用是0元）。12月30日中午出了结果，马上在网上申报，下午三点获得了必须的绿色行程码。12月31日早上5点起床，7点到达机场出发大厅，发现机场内人潮汹涌，正值日本新年假期出行高峰，办任何手续都得排长队，回国更是要”过五关斩六将“，到达登机口时已经九点了，离起飞时间只差半个小时。
