Have you applied for a patent for printing bicycles?

In China, bicycles were obviously invented by us. Why do Germans apply for patents? This question is puzzling. In fact, I think the most important thing is that although China people invented bicycles, they did not continue this technology, but only made the initial prototype. As soon as the Germans invented the bicycle, they immediately applied for a patent. It is well known that everyone thinks that bicycles were invented by Germans.

And then we were curious. Which great man in China invented the bicycle? After all, the traffic was not very developed before. If you have a bicycle, it is a good means of transportation.

As we all know, Edison was a great inventor, but no one knew that Huang Lvzhuang was also an inventor in the Qing Dynasty. He invented the world's first bicycle, the first thermometer and the first searchlight. Many of his inventions are hundreds of years earlier than those in the west and much more powerful than Edison. But not many people know him, and certainly not as famous as Edison.

Let's take a look at Huanglvzhuang, a native of Yangzhou, which was a trading port at that time. So he came into contact with some scientific and technological works written by European missionaries and learned a lot about geometry and physics. In addition, he is very talented and has a hobby of making things by hand, which laid the foundation for his future inventions.

According to the historical records of China, Huang Lvzhuang made bicycles. It is recorded in the book that there are two wheels in front and back of the bicycle, which is more than one meter long. People can move forward just by shaking the crank bike.

Now it is the Germans who apply for a bicycle patent. Obviously, China people invented bicycles as early as 200 years ago, but the patents were taken away by foreigners. Now I feel a little unhappy when I think about it.
