After World War I, Lu realized that America had become the center of the antique market. He decided to open the largest antique shop in the United States with Shanghainese Wu at the corner of Madison Avenue and 57th Street in new york. His fame and connections soon made him a supplier and consultant to many private museums. Since 19 15, Luwu Company has exported cultural relics to the United States for 30 years, and there are countless national treasures. Only a small shareholder of the company can get hundreds of thousands of silver every year. At that time, the annual flow (total sales) of an antique shop in Liulichang was not so much!
