Shanghai was brought to a standstill on Monday by what authorities say was the strongest typhoon to directly hit the Chinese financial hub in more than seven decades, with flights, trains and highways suspended during a national holiday.

Officials in China moved some 414,000 people out of the way in Shanghai before the strongest storm in decades flooded roads and cancelled flights.

Parts of China are preparing for a fresh tropical storm, just days after the country’s eastern seaboard, including Shanghai, was hit by the strongest typhoon it had seen in decades.
