Zisha Appeal, Cystal Light, and Top Yixing Zisha Clay Teapots

Good Yixing Zisha teapot should have "Zisha Appeal" after long term usage.  This Zisha Appeal is closely related to what ZHOU Gaoqi said about "Guang (Light)": JingGuang, RunGuang, and HeShang (Monk) Guang.

周高起曾说过“砂壶，有晶光者，最为上乘，有润光者，上乘也，和尚光者，最为贼相。”如果新的紫砂壶给你的感觉就是贼光艳色，那一定是假的。好的紫砂，表面晶光，颗粒均匀，分布比较规矩，在强光下内敛沉稳，上手有润度。润光也是蛮好的，实用器的选择。和尚光就是发贼，不用看了，肯定是假的了

Zhou Gaoqi once said, "Sand pots with crystal light are the best, those with moist light are second, and those with monk light are the most thieves." If the new purple clay pot gives you the feeling of brilliance, it must be a fake of. Good purple sand has crystal light surface, uniform particles, relatively regular distribution, introverted and steady under strong light, and moist to the touch. Runguang is also pretty good, a practical choice. The monk is just a thief, don't look at it, it must be fake
