Okay kiddo, have you ever played with Legos before? You know how you can build anything you want with them by connecting the pieces together? Well, cement is like the Lego of the building industry. It helps hold things together so they don't fall apart.
In Taiwan, there are big companies that make a LOT of cement. These companies mine for certain minerals that they need to make cement, and then they mix them together in a big machine to create a powder. This powder is then shipped to construction sites all over Taiwan where it is mixed with water and used to build things like roads, bridges, buildings and walls.
The cement industry in Taiwan is really important because it helps keep the country running. Without it, people wouldn't be able to build new things or repair old buildings, and the country would not be able to grow and develop. However, it is also important that the cement industry takes steps to protect the environment while making cement. That means reducing pollution and using resources efficiently, like using recycled materials to make cement whenever possible.
So, in short, cement is important because it helps create strong buildings and roads, and the cement industry is critical to making that possible in Taiwan.
