What's it like to work in Huaqiang North?

I have been in Huaqiang North 15 years. It was really hard to work at first, but I lived a full life and worked in the electronic market. You can earn about 200 thousand by running alone for a month. Sleep for two or three hours every day, without eating or drinking. Later, I saved more than 30 million. It doesn't feel good to come out and do some small business on the spot. Shenzhen is a good city to make money. As long as I can bear hardships, I have plenty of money.
