In fact, the glass lamp is not an instrument that hides mystery. On the contrary, the glass lamp is just an ordinary container for holding things. If others break it, they will not be punished by going to heaven at all. The key point is that the Jade Emperor was very dissatisfied with Friar Sand at that time, so even if Friar Sand did something wrong at that time, the Jade Emperor would choose to punish him. So it's not that this thing is precious, but because he was already a thorn in the jade emperor's side. If he doesn't handle it properly at this time, he will be banished to the sky sooner or later.

Finally, because he didn't do his duty, he broke the glass lamp and was banished to Liushahe, where he was punished. In fact, in our opinion, Friar Sand is an upright and honest person, but people before him don't think so, probably because his personality has changed a lot after such treatment. Because his words and deeds will bear great responsibility, so be careful. He always asks his brother what to do before he dares to do anything.

This fully proves that he was also targeted by other people in heaven. What's more, he doesn't do his duty at ordinary times, because his duty is actually to roll curtains, so he is called the general who rolls curtains. Such a personal bodyguard can't help the Jade Emperor much. And in front of the jade emperor, he is also a condescending figure. Even when the Monkey King wanted to make a scene in heaven, he chose to avoid it and then didn't fight. Because the Monkey King made a scene in the sky, the Jade Emperor was very dissatisfied, but he couldn't deal with the Monkey King well, so he got angry and had to take it out on Friar Sand.

Some people say that the glass lamp also contains these precious medicinal materials, so if Friar Sand breaks such things, it must be a great waste and a great pity, so the Jade Emperor intends to send him to heaven and give him a serious execution.
