Why should Wei Di take a pill, and where do the seven bowls of tea in Lu Tong come from?

The whole poem:

It shows that Wei Moyuan is not ill, but he has forgotten his home at home.

There is no need for Wei Di to take one pill and use seven bowls of tea in Lu Tong.

Vernacular translation: When Vimal, a monk, fell ill, the elder Vimal knew that Manjusri and his disciples would come, so he used his divine power to empty the room and became nothing but a bed. When Manjusri Bodhisattva entered the room, she asked the elderly in Vimalakīrti about her illness. Xie Lingyun is already roaming around among the vulgar people. Where we need Wei Di's elixir of life, we only need seven strong teas in Tang Lu's poems.
