Wonder of China

[Janjoy]

Hi everyone - my first time on this community board. I took my first trip to the Deep South, USA, about 4 years ago with Just You and spent the new year in New Orleans. I had the most fabulous time ever. We were on the Mississippi River for New Years evening watching the fireworks go off around New Orleans ! There were 18 of us and the ages again ranged from mid 20s to mid 60s and we all had a great time together. Laughing and drinking and eating in B B Kings restaurant !!! Well anyway....I was thinking of going to China but wanted to know if its a lot of strenuous walking. I have a dodgey knee as the result of a cycling accident and didnt know if it would stand up to it. Other than that Im a fit 58 year old !!! Can anyone let me know what they think please?
