In the preschool stage, the perception and experience of young children are very important. The essence of WeLAI Study is to cultivate the thinking ability of young children. If incorrect answers are marked with an "X" or any other mark, it can give the child a negative hint, affecting their enthusiasm and initiative in thinking. Therefore, in the guidance methods of WeLAI Study, it is essential to note that when a child makes a mistake, nothing should be written; instead, just tell them "Think again, observe more carefully". There's no need to rush for the child to get all questions right at once. They can have another try in the next practice session.

In the heart of a child, these two sentences should be deeply ingrained: "Even if you can't do it, as long as you think about it, you will become smarter! Even if you don't know how, as long as you try your best, you will become smarter!"
