>Greta Thunberg in tweetstorm
Swedish climate campaigner Greta Thunberg has been taken to task by a German railway company after tweeting a photo of herself sitting on the floor at the end of a train carriage surrounded by suitcases and backpacks.
The 16-year-old drew sympathy after posting that she was traveling on "overcrowded trains" on her way home from the UN climate change conference in Madrid.
Responding, rail operator Deutsche Bahn said it was pleased to have her on board their eco-friendly train and welcomed her support "in the fight against climate change".
But the company added: "It would have been even nicer if you had also reported how friendly and competently you were looked after by our team at your seat in first class."
Thunberg was recently named Time magazine's Person of the Year for her efforts to press governments and others to take more rapid action in combating climate change.
>737 MAX production halted
US airplane giant Boeing Company announced Monday it will temporarily halt production of 737 MAX jets beginning in January.
The decision, made by Boeing's board, follows news last week that the Federal Aviation Administration would not approve of resumed flights of the 737 MAX airplanes before 2020.
It did not announce any employee layoffs as a result of the suspension decision, saying the workforce related to the 737 MAX production at its final assembly facility, Washington State, will be temporarily assigned to other teams in Puget Sound.
More than 800 jets have been grounded worldwide since mid-March 2019 after investigators found flawed flight control software on the 737 MAX partially responsible for the crashes of two MAX jets in Indonesia and Ethiopia.
>Vaccine system gets deadline
China has required the completion of a national vaccine tracking system before March 31, 2020, to enable the whole-process traceability of all vaccines on the market, according to a recent circular. The circular, jointly issued by the National Medical Products Administration (NMPA) and the National Health Commission, specified the responsibilities of the NMPA, provincial drug regulators, provincial health authorities and authorized manufacturers in building such a system.
The NMPA is working to launch a collaborative service platform, which will be connected with online systems for immunization programs and those for vaccine data, to integrate information of vaccine production, circulation and inoculation, the circular said.
The NMPA and provincial drug regulators will build the national and provincial supervision systems for vaccine traceability, it added.
Beijing, Tianjin, Inner Mongolia autonomous region, Shanghai, Jiangsu, Hainan and Chongqing were pilots in building the system, the circular said. These provincial-level areas were required to connect regional vaccine tracking systems with the national collaborative service platform before Dec 31, 2019, and begin to feed the platform information by Jan 31, 2020.
>92 foreign students expelled
Wuhan University in Hubei province recently expelled 92 overseas students.
Hu Yanchu, head of Wuhan University's School of International Education, said these 92 students were undergraduates and graduate students.
Some of the students were expelled for having failed to register within the stipulated time, some for skipping mandatory school activities without submitting leave applications and some for failing in their academic courses.
The university would examine foreign students twice a year since 2014, and in past years, some unqualified students have been ordered to leave. In 2017, 184 students were ordered to leave, and in 2018, there were 109.
In recent years, the country's education authority has issued regulations to require universities to strengthen the management of foreign students, to not only attract more students, but also keep an eye on quality.
