On the composition of street typos

The school teacher assigned an assignment to take pictures of the typos in the street. On this day, my mother and I are going to her factory, and I feel a little sick in the middle of the car.

So I asked the workers in the factory, and she said: Oh. What public toilet? This is obviously a public rule! So I asked again: This brand has been written for many years! She said, "I don't know. I had it as soon as I arrived. It's been a long time anyway. I can't help sighing that this typo hasn't been changed for so long.

My mother said, "In fact, there are many typos in the street, but they have not been found. I was a little angry after listening to it.
