People have the chance to own a piece of Hollywood history. On Nov 23, an exciting auction (拍卖) will take place. People can buy many cool things from famous Hollywood movies and stars, and some of them have never been sold before. But owning a piece of Hollywood history can be expensive. For example, the dagger (匕首) with which Kit Harington kills Daenerys in the popular US TV series Game of Thrones (《权力的游戏》) will sell for 19,000 pounds (about 174,800 yuan).
