Is the Jin River in Beijing easy to enter?

It's hard to get in. Beijing Jinhe Water is called Beijing Jinhe Water Construction Co., Ltd., formerly known as Beijing No.1 Water Conservancy Engineering Office. Now it has developed into a comprehensive enterprise group with water conservancy and hydropower engineering construction, architectural decoration and component production as its pillars. The recruitment requirements of the company are college degree or above in water conservancy and hydropower or related majors, with more than 3 years of construction management experience in water conservancy and municipal engineering, and a first-class constructor certificate (water conservancy and hydropower), which is difficult to enter.
