Harbin industry or Zhuhai.

Zhuhai has many industries. Because Zhuhai is located in the Pearl River Delta and the local industrial environment is relatively good, many enterprises are willing to develop related industries in Zhuhai, so Zhuhai's industry as a whole develops well, while Harbin is located in the northeast and the weather is cold, which is not suitable for perennial development. Many companies are unwilling to set up industries in Harbin, so the overall industrial development is relatively backward, and the number of industries is obviously much less than that in Zhuhai.
