I want to know the answer to the following question:
What did China trade with Tibet and Mongolia?
All the background I'm provided with is that "The department's original purpose was to manage the internal affairs of the imperial family and the activities of the inner palace (in which tasks it largely replaced eunuchs), but it also played an important role in Qing relations with Tibet and Mongolia, engaged in trading activities (jade, ginseng, salt, furs, etc.), managed textile factories in the Jiangnan region, and even published books.". Is that enough to answer the question?
Answer: yes
