May 1 1 day was successfully planned. The next day, Duke Zhou came to Luoyi, made a comprehensive inspection of the planning of faithfulness and divination. Divination shows that the construction of a new capital in the west of Zhuoshui, east of Jianshui and on the bank of Luoshui will be a great success. It took about a year to build. The city is 1720 feet, and the outer city is 70 miles. The palaces in the city are magnificent, and the new capital is called "Xinyi" or "Silla"; Therefore, there is Mangshan Mountain in the north of Hubei Province, so it is also called Mangshan Mountain.

In the eastern suburb of Xinyi, the residence of Yin people east of Zhuoshui is called "Chengzhou", which means to achieve Zhou Dao. The original Haojiang River was called "Zhou Zong".
