Shenyang was an important town in Liaodong in Ming Dynasty. When Nurhachi chose Shenyang as the new capital, Shenyang was already in the hands of jurchen. Shenyang is a medium-sized city with relatively flat terrain and few people, mainly because of its superior geographical position, which plays an important role as a military base.

Therefore, in addition to the reasons of geomantic omen, the strategic position of Shenyang, in Nurhachi's view, is also the king of Khan, and it is also unreasonable in face that it does not have its own big palace. So Nurhachi decided to build his own palace, the Forbidden City, in Shenyang. When Nurhachi made this decision, the first person who came to mind was Hou Zhenju, who once gave himself a glass jar and a blue glaze bowl.

Hou Zhenju is a skillful craftsman, and his glass products are the best in the world. Therefore, as the designer and builder of Shenyang Forbidden City, Hou Zhenju began to work with many craftsmen.

Unfortunately, Nurhachi didn't keep Lu long enough. He died as soon as he decided to build a house. /kloc-in the autumn of 0/626, Nurhachi died before he could conquer. The cause of his death has also become a great mystery in history.
