It was completed in 1412, a long while after Liu's death, with a preface added by the Jiao in its Nanyang publication.
Although an ancient hematite artifact from the Olmec era in Mexico dating to roughly 1000 BC indicates the possible use of the lodestone compass long before it was described in China, the Olmecs did not have iron which the Chinese would discover could be magnetised by contact with lodestone.
Although it is recorded that the Han Dynasty (202 BC – AD 220) court eunuch Cai Lun (50 AD – AD 121) invented the pulp papermaking process and established the use of new materials used in making paper, ancient padding and wrapping paper artifacts dating to the 2nd century BC have been found in China, the oldest example of pulp papermaking being a map from Fangmatan, Tianshui; by the 3rd century, paper as a writing medium was in widespread use, replacing traditional but more expensive writing mediums such as strips of bamboo rolled into threaded scrolls, strips of silk, wet clay tablets hardened later in a furnace, and wooden tablets.Tags: Adult Dating, affair dating, sex dating
