Cangjie, duplicate surname Hou Gang, named jie. Legend has it that in ancient times, Cangjie had four eyes. He served as a historian in the Huangdi Period. He was later invented by the footprints of birds and animals. He was called a "literary sage".
Cangjie has made two great contributions in historical records. One is to create characters, the other is to discover River charts(chinese pinyin:he tu).
Legend has it that Cang Jie was an official under the Yellow Emperor. The Yellow Emperor assigned him to specialize in the number of livestock in the pen and the amount of food in the tun. But slowly, the storage of animals and food is gradually increasing and changing, and can not be remembered by the head alone. Cangjie is in trouble. Cangjie spent the whole day and night trying to figure out how to tie knots on the ropes and use different colors of ropes to represent different kinds of animals. But for a long time, it won't work. During a hunting trip, when we reached a fork in the road, several old people argued about which way to go. An old man insisted on going east, saying that there were antelopes; an old man wanted to go north, saying that the herd of deer could be caught not far ahead; an old man wanted to go west, saying that there were two tigers, and if they did not kill in time, they would miss the chance. When Cang Jie asked, it turned out that they all looked at the footprints of the underground beasts. Cang Jie was overjoyed: since a footprint represents a wild animal, why can't I use a symbol to express what I care about? He ran home happily and began to create various symbols to express things. Sure enough, manage things well. When the Emperor knew it, he greatly appreciated it and ordered Cangjie to teach this method to various tribes. Gradually, the use of these symbols has been popularized. In this way, chinese words are formed.
One legend about the river map is that Cangjie went south to hunt his territory and climbed the Yangxu Mountain. As the Luohe River went east to Luoshui, where Luoshui and the Yellow River meet, he found that the tortoise carried a mysterious pattern and presented it to Cangjie, which is the so-called River charts (chinese pinyin:he tu).
