Furthermore, keen observation is the only way to train one's vision, so you should always take the opportunity to observe and to minutely appreciate things. Perhaps after a while you might discover that the teacup that you had originally been using was not so ideal. After countless viewings of hundreds of teacups, you would unconsciously develop a keen, aesthetically discriminating eye.
多看，是訓練眼光的不二法門，儘量多看、細賞，可能過一陣子，你會發現原來的杯子不盡理想，再經過若干次的探訪，看過數百只杯子，不知不覺中，你就會養成敏銳的審美眼光了。
