For the city of Liverpool, I only know football and the Beatles. But when I walked into the city, I found that the surprises that brought me did not stop there. It is like the episode of the rise and fall of Great Britain. Nowadays, nearly 3,000 buildings in the city were built in the 18th century, and the heavy sense of history can be felt everywhere in the streets. Walking on the street, you can also see Liverpool's logo: a bird called the liverbird. But because the image of the first liverbird in history has never been recorded, the whole Liverbird that Liverpool can see is not the same.
