A concept that needs to be emphasized is "from quantitative change to qualitative change." The roofs are made of a very new material; it can produce the largest span and the largest volume of space. But it also has shortcomings. For example, during typhoons, or when it rains, there is an echo problem.
需要強調一個觀念是「量變到質變」，薄模是很新的材料，會產生最大的跨距，最大的空間量，但它也有弱點，像面對颱風，下雨很吵、回聲等問題。
