About a week ago, I went to the China Jiade International's Autuman Auction. Among lots of various things, I found a weapon. It was called "金刚撅", actually, was for Buddism. It looked very old, compared with those shining china

with a lowest bidding price of 50000 RMB. I checked it carefully, making sure if it was really a early-Ming piece.
Weapons on auction win quite different popularity in different regions. I noticed in Beijing Hanhai's Spring Auction, all six swords hadn't found buyer. But in many auctions at Guangdong Province, the deal on weapon is very hot.
