Developed coastal areas. The main reasons why the economies of these places are relatively developed are as follows.

First, the tilt in economic policy.

As we all know. The most critical reason for the development of developed coastal areas, such as Shenzhen, is that policies are particularly tilted in this regard, and the country has implemented preferential policies in many aspects. Energy can greatly promote the creativity and imagination of local people. Because they dare to think, do, and fight, they have made great progress in the economy, political and cultural construction and other aspects.

Second, it has a profound economic foundation.

Since ancient times, the south has been a prosperous region. After nearly a thousand years of accumulation, it has had a great advantage over the north in terms of economy and culture. The South's dense population and developed culture have always been much superior to the North economically. In the past dynasties, the harm suffered by wars in the south was much less than that in the north. Because war has the greatest destructive power on the economy, the South has suffered relatively little trauma in the wars of past dynasties. As a result, the southern production economy, construction, etc. suffered less damage. This economic condition laid a solid foundation for their subsequent economic take-off.

Third, the south has very developed and convenient transportation.

The southern region has very extensive exchanges with other countries in the world. In addition to the Han Road, maritime transportation is also very developed. In addition to trade with overseas countries, maritime resources are also extremely rich. Therefore, during most disaster years, southerners rarely go out to escape. First, when encountering a war, southerners can escape and reach other countries in the world through sea transportation. This is a condition that residents in the interior do not have.

Fourth, the south has a very rich and developed culture.

The cultural development of the South and other countries is the result of historical continuation. The Chinese nation's ability to tolerate various cultures from other countries in the world is inseparable from the open thinking of southerners. Most of the gentry officials in ancient China were from the south. Since southerners had the most frequent contact with overseas cultures, they were able to tolerate different types of cultures from various places, which also made their thinking sharper.

The southern coastal areas mainly occupy very superior geographical conditions and convenient transportation conditions.

At the same time, coupled with their profound cultural heritage, the southern economy is very developed.
