EYWA's main functions are divided into two main parts: stand-alone and online use. When used alone, EYWA will act shyly when it senses that you are touching it; when used online, it will react the same way despite being in a different place. In this way, the concept of guarding a tree together is achieved.

As a small tree as a daily existent, people will water it every day, I hope to make a small tree that needs to be watered with our communication with our parents, the health of the tree reflects the health of our commu- nication with our parents, and it will also give feedback to our actions individually. Of course, the communication is not one-way, we need to work together with our parents to guard this little tree, the little tree will be healthy and grow.
