Before leaving, Jobs gave Cook a tip bag and repeatedly told him to only open it when Apple’s hardware was slow to sell and the stock price plummeted. Cook finally couldn’t stand it anymore and opened it in 2019. There were four words written on it. One word: If the hard one doesn’t work, try the soft one.

The Tang Dynasty implemented a system of three provinces and six ministries, but the Secretary Province was not among the three provinces. The so-called province originally meant the imperial palace, but later evolved into official offices. Therefore, the official offices called provinces in the Tang Dynasty were all located around the imperial palace.

The concept of province as we understand it today, such as Anhui Province and Zhejiang Province, was established from the Yuan Dynasty and the Ming Dynasty.

The Secretariat is in charge of the royal library and archives work. This is the tradition of the Eastern Han Dynasty. At that time, all the books and archives were copied by hand, and many of them were collected by the royal family and could not be seen by outsiders, so they were called "book secretaries", or secretaries for short.
