《太平广记·卷三·神仙三》
三天太上道君又根据山脉的走势和河流的四射盘旋形状，创造了文字，这种文字是以象形来表达实际存在的事物。
乃因山源之规矩，睹河岳之盘曲，陵回阜转，山高陇长，周旋逶迤，形似书字，是故因象制名，定实之号。
On the third day, the Supreme Master of the Tao created a script based on the trend of the mountains and the meandering shape of the rivers, and the text expressed the actual existence of things through pictograms.
