Can anyone tell me why there are holes in the lids of old purple clay teapots? Why are there no holes in the current ones?

There are holes on the purple sand: during the tea making process, you can better enjoy the aura and aroma of the tea. Some modern purple clay teapots do not have holes: this is to allow the aroma of tea to hit your face after making tea, making the aroma more intense! In fact, whether there are holes or not depends on personal preference. The highest state of playing with purple clay pots is: having something in your hands but nothing in your heart!
