Hi, Hengyu By reading your blog, I think I have deepened my understanding of ULD. This new learning method can effectively improve the learning environment of disabled students. At the same time, I believe ULD and UID are inseparable. In your blog, you made a specific general discussion about your own experience, which enabled me to bring it into the whole article and deepened my understanding of ULD. Although this way of learning that can reduce barriers is only suitable for particular groups, for the time being, I believe it will play a more significant advantage in the future.
