Take Dandong as an example, it is a border city, mainly relying on exports, and needs the convenience of traffic conditions to bring about relatively rapid economic development, thus driving the rapid economic development of the mainland.

Why are port cities more developed? Because they have convenient transportation conditions.

As the saying goes, to get rich, build roads first.

Poor local traffic will lead to slow economic development. Isn't it very distressing that things can't be shipped out?

Therefore, the national government invests a large part of funds in transportation every year to promote economic development.

Narrow roads will bring a lot of inconvenience, and naturally no one will invest.

Economic development will not be good.
