In late summer 2019, I had the opportunity to travel to Shanghai, China to staff a software exhibit at a conference there. My favorite travel companion (aka my wife) decided that she didn't want to go on this trip, so I was on my own.
I decided that, after my gig at the software exhibit was done I would travel to Beijing to spend a couple of days touring and then spend two days hiking on a remote section of the Great Wall of China.
The Bullet and Me
To get to Beijing from Shanghai, one can either fly or take a train. I've taken enough flights in my life to know that experience well. What I haven't done, however, is take a "bullet train".
I again went to the expert on train travel at the "Man in Seat 61" website - https://www.seat61.com/China.htm - for advice and found that there are several of these high-speed trains that run both ways, every day, between Shanghai and Beijing. The cost of a Business Class seat on the Shanghai to Beijing bullet train is about same as coach airfare between those cities, so what choice did I have?! I booked a seat.
Once I was done with my conference staffing duties, I took a taxi to the Shanghai train station; the largest train station in Asia. Once I gained entry to the station, I had to find my train. Here is a video of the inside of the largest train terminal in Asia.
