How to apply for a patent in Longgang

I'm from Longgang Central City. Last month, I applied for a patent to make a car. I can't disclose the details, because I'm also applying. Haha, I found Shenzhen Landun Intellectual Property Agency Co., Ltd. on the Internet. It is said that Landun Company is good. Then I went to Blue Shield Company to have a look, and it was really good. Blue Shield Company is in Chegong Temple, Futian District. I saw it at Exit C of the subway entrance. It is easy to find. Blue Shield's colleagues in Shenzhen are also quite good. Don't look for some small companies outside the customs. No money, no good deeds. The price is almost the same. Go and see for yourself. Baidu Landun's patent application found Landun's website, which is very formal and professional.
