Really good writing, I suggest

you write a book about your experience traveling around the world. With so many journals you kept and so many pictures taken during your trip, it can be a very easy task for you. I have read many of your postings here, I think your writings is equally good in Chinese and English, they are all very natural, smooth, interesting and truly enjoyable. Just being curious (maybe a bit prying), I wonder how you can manage to spend so many time to travel, are you not working, maybe born-rich?
