The most valuable thing to a person is youth... Travel when you are young... so that when you are an old man like me, you have memories to keep...
Glad you enjoy your trip.. Not many people have pleasant experience in China. Amid all the pollution, choking fumes, crowds, super bad traffic, people talking loudly, people spitting every where, touts coming up to you trying to rip every cent out of you... China does have a 5000 year history which not many culture and other parts of the world have.
Beijing is a nice place... if all goes well, will bring my boys there this autumn.. Peking Duck... Shuan Yang Rou (涮羊肉) yumm yumm...
