The book signing was held in Hefei on October 1, and I went there that day. Those with signatures can only be bought at autograph sessions, or bought from others. Signing is 60. The official forum vaecn sells it for 49, with free shipping. This book is a collection of photographic essays, mainly some pictures he took when he went to Greece. Some pictures are accompanied by some casual writing. The poster can buy a copy for collection, if you like Xu Song
