I hadn't realized I'd have a 20 hour layover iin Beijing, people laughed at me, told me about exclusive lounges I could book online for a sleep. But what they and I didn't know was China now gives you a one day visa to the city. And me knowing Beijing I was back like a duck in water.......funny how life works out. Me with 20 hours to re-explore Beijing, my third visit. 1st time one week, 2nd time 1 week, 3rd time 20 hours.
