Why is Shantou backward?

It is a cliche that Chaoshan people are flexible, disdainful of working, and most of them do business by themselves, starting from childhood. Shantou is a special zone in the 1980s. With the support of zc, Shantou is close to Hong Kong and Macao frequently, gaining development opportunities and developing rapidly. But Chaoshan people are usually short-sighted, want to make quick money, and even dare to do illegal things, such as smuggling and counterfeiting. At first, they didn't seize the opportunity and lay a good foundation. Now there is no decent industry in Shantou, and the manufacturing industry is in ruins. Handmade workshops are everywhere, and Chenghai's toys, wool and Chaoyang's clothes can all become China's brands (the brands here do not refer to registered trademarks, but have a certain popularity, such as Audi). Scientific and technological progress, convenient transportation, no longer obvious geographical advantages, no zc support. The airport high-speed rail has forgotten Shantou. Foreign capital invested in Jiangsu and Zhejiang, and local tyrants emigrated (going abroad or moving to big cities), taking away a lot of money. Shantou wants to develop, there is no zc outside, there is no geographical advantage, there is no money to develop, and the existing industries are gradually backward and eliminated. What should I do?
