In February of the last year, Yushui inkstone was built. Inlaid in green, carved in cyan, hooked in Zhu Mo. (I) personally went to the mountain to carve stone, because they couldn't carve stone, so they humbly gave it to me.
Hook, the brushwork of Chinese painting, refers to drawing an outline with lines. Use a pen to "hook" the trend, and use a pen to "hold" the trend.
