I am travelling Shanghai in May 2020 with a tour group which is originating from USA.

Anj, could you, please, offer some details regarding your itinerary? Like this, all that we know is that you will depart from US and that your trip starts in Shanghai and ends in Beijing.

To be able to offer you a correct and reliable answer these are the details that we need:

1. Type of your flight to Shanghai. Is it a direct flight from US to Shanghai or does it have some other stops en route?
2. An itinerary for your trip, I assume a cruise. Does it goes along the Chinese shore, visiting Chinese cities like Qingdao, Dalian... or it departs from Shanghai goes to some other countries and ends in Beijing directly from abroad?
3. Type of your flight out of Beijing. Is it a direct flight to US or does it have some other stops en route?

I apologize for asking instead of answering, but your initial query simply does not allow to offer you a decent answer. Thanks.
