答案
Hello, everyone! I'm Li Hua. I have been fond of inventing since I was a little child. The invention I most want to make is called "Smart Temperature-adjustable Jacket".
It is used to keep people in a comfortable state all the time. People no longer need to frequently change thick or thin clothes when seasons change, which is very convenient.
It will be made of special smart fabric. The fabric can sense the temperature around, and automatically adjust its own temperature to keep us warm on cold days and cool on hot days. It will be very light and comfortable to wear.
