Sacramento was originally a castle built by Swiss immigrants. Marshall accidentally found gold in the local river when he built a sawmill in January 1848, and the purity was very high. After the news came out, it shook Europe and the United States, and gold miners from all over the world poured into California. The historic gold rush was sparked. Sacramento quickly became a major economic hub from a small town, where the first rail terminal was built across the United States mainland. At the same time, I also quoted a funny Chinese place name here, because my mother can't remember the pronunciation of Sacramento, so Ronaldinho said that there was a star in the interview that he came here, but the pronunciation was inaccurate, and it was said that it was three gimmicks. So, my mother remembers it!
