How do I know through these clouds? What is the next sentence?

There is no next sentence, only the last sentence, the last sentence is: but which corner of the mountain. I only know that it is in this mountain.

Jia Dao [Tang Dynasty]

Original text:

When I asked your students under a pine tree, "my teacher," he replied, "went to pick herbs."

However, through these clouds, how can I know which corner of the mountain it is facing? .

Translation:

Cangsongxia asked the young schoolchildren, and he said that his master had gone to the mountains to collect medicine.

I only know that it is in this mountain, but I don't know his whereabouts because there is fog in the mountain.

"But through these clouds, how can I know which corner of the mountain it is facing? In the last two sentences of the poem, he also told me that it is in this mountain, but the forest is deep, and I don't know his whereabouts. Here, the question "Where are the herbs?" Omitted, and the boy who answered "but to which corner of the mountain" implicitly contained the question. The last sentence, "How can I tell through such a cloudy day?" It is the boy's answer that collecting medicine is in front of the mountain, behind the mountain, at the top of the mountain and at the foot of the mountain.

In this poem, it is obvious that three questions and answers can only be expressed in at least six sentences. Jia Dao adopted the method of setting question-and-answer sentences and simplified them into crosses. This kind of "scrutiny" is not between the lines.
