Then I saw 2 mormons, I smile at them and one of the foreigners talked with me, I asked him their difference with 耶和华见证人。He gave me the book of Mormon. I gave him my email address. At first I intend to practice my English but then it is found that he speak Mandarin well. So I ended up practicing Mandarin.

The term "Mormon" has its origins from the Book of Mormon, which is believed by Latter Day Saints to be a collection of writings and teachings of the ancient prophets and followers of Jesus Christ who lived in the Americas from approximately 600 B.C. to A.D. 421. Mormons believe that Joseph Smith, Jr. translated the Book of Mormon into English by divine inspiration from golden plates that he received from the angel Moroni. Mormons believe that the Book of Mormon is another scriptural witness of Jesus Christ that is comparable to the Bible, which they also believe to be the word of God.[1] The book gets its name from Mormon, the prophet who abridged the record during the 4th century.
According to the Oxford English Dictionary, one of the earliest published usages of the term "Mormon" to describe believers in the Book of Mormon was in 1833 by the Louisville (Kentucky) Daily Herald in an article, "The Mormons and the Anti-Mormons".[
