I have just read on the Internet a German newspaper (FAZ). To have an impression what is going on in big parts of southern and central China have a look at the pictures and the video. A friend of mine who works here in Wuhan was on Tuesday stuck in Beijing; no train, no plane back to Wuhan. And tomorrow he would like to leave for vacation.
He is one of millions of people who are stuck due to the exceptional winter. The reason why so many people travel is the Chinese New Year, the main festival here in China. And a lot of so-called migrant workers have only once a year the opportunity to visit their family.
