預鑄就像是大型建築的積木，在工廠將積木製造出來後，在工廠立組裝，當確定組裝沒有缺點，再透過風雨實驗，看看每個細節的接合處，是否有漏水的情形，全部都沒有問題後，才包裝出貨。

Precasting is like the building blocks of large buildings. After the building blocks are manufactured in the factory, they are assembled in the factory. When it is determined that there are no defects in the assembly, and then through the waterproof experiment, see whether there is water leakage in the joint joints of each detail. After all there are no problems, they can be packaged and shipped.
