A sad thing happened in Taiwan on Friday. A man used a knife. This happened in the big city. It was at a train station. Three people died. Nine people were hurt. The man was 27 years old. His name was Chang Wen. He fell from a building and died.
The attack was in the evening. Many people were at the station. The man walked to a shopping place. People were afraid. They ran. Some videos show people running. The man had knives. He may have started fires.
Leaders think it was planned. They want to know why. Chang Wen had problems before. He did not do his military service. This is very bad.
Taiwan is usually safe. There is not much crime. This attack is a surprise. The government will make things safer. The President will be strong. People do not feel safe now.
Help came fast for the hurt people. One person was brave. He tried to stop the man. He died. Police are looking into it. They want to know more. They help the people and their families.
