You are right. In Taiwan, there are indeed many places where seals are used. And they are very important. In Taiwanese life, seals can be said to be second only to ID cards.. and even to Identity cards are equally important... For example, when you get assets and important documents, you need your seal and ID card. But now there are fewer seals. In Taiwan, ID cards are still the main thing... I only remember that when I When I was a child, I used to use seals a lot to do things. Now I can just take my ID card..
I hope my answer can help you
