About thirty years ago, China was known as the “Bicycle Kingdom”. But the two-wheeled way of transportation became less and less popular later.

But these months you can see a revival(复兴) of bikes across China. More and more people choose to ride bikes instead of driving to schools, workplaces or parks. Some start-up companies(新兴公司) like Ofo and Mobike came up with the bike-sharing plans. They have brought the plans to people’s daily life and developed it to a new level.

Unlike other sharing plans around the world, China’s bicycles can be picked up and left anywhere. The bicycles are locked by the user after riding and then unlocked by the next rider by using a mobile APP and scanning(扫描)a QR code on the bike.

People can unlock the shared bikes by simply using their smartphones. The bikes have GPS and can be left anywhere in public for the next user. They’re popular among many Chinese people as they provide a good solution to the “last mile” problem, which means the final leg of a person’s journey.

China’s government praised Mobike and Ofo last month. They said that bike-sharing was a good way of cutting air pollution and traffic pressure.

You know, having a dangerous medical situation will happen during all of our lives. What I want to talk about is how to stop a bleeding nose.

The first step is to have the person sit quietly while you perform the steps of stopping the bleeding nose. Soft paper can be placed into the two holes at the end of your nose that is bleeding. Make sure that you don't place too much soft paper in, as you may not feel comfortable when you move the soft paper away from the holes in the nose.

Then hold your nose together between your thumb and finger at the cartilage(软骨)area where the bridge of the nose is hard. That will make less blood move to the holes in the nose. After five minutes to twenty minutes, the nosebleed should come to a stop. After the nosebleed stops, the soft paper can be moved away. Another way that commonly works is to place a piece of ice under the lip between the gum(牙龈)and the lip, as this will reduce the size of the blood vessels(血管)leading to the nose. If it is too late to take any action, the head should be raised where blood can be moved from the hole in the nose to the stomach area.

I'm Joe Bruni. Stay safe, and come to see me if you are in trouble with healthy problems.
