I found the following information on this website related to transit visas (see below). Does anyone know where I can find this information from an official chinese government website to confirm it?

"Visas are not required for passport holders of the following 20 countries, who transit through Pudong Airport or Hongqiao Airport or seaports of Shanghai, provided they hold valid passports, visas and tickets to the final destination and have booked seats, and stay in Shanghai for less than 48 hours (going out of the airport is allowed): United States, Canada, Australia, Germany, France, New Zealand, Netherlands, Spain, Italy, South Korea, Belgium, Luxemburg, Portugal, Austria, Greece, Sweden, Denmark, Norway, Finland, Iceland."

My situation: I'm Canadian and will be flying from Tokyo to Shanghai. I will be staying in Shanghai for 26 hours and then flying back to Canada and I am looking for some sort of official confirmation that I don't need a visa because I don't want to be stuck in the airport for the entire time.

Thank you,
