After taking PCR (rapid PCR at Prenetics at the airport, or standard or express one at a regular site), do I need to wait there for the result?
Can I take transportation to go to west Kowloon railway station (the station that has high speed train bound to Guangzhou?), in order to catch a train from Guangzhou to some place in time once the result comes out as negative?
I won't have mobile service there. If I can receive the PCR report in SMS or email, does entering the mainland require a PCR report in paper? Do I need to print it out and is there printing service near the station?
Thanks.
