After Ao Bai was removed, it took several years for the Qing Dynasty to finally stabilize. Seeing that the emperor was going to implement various reforms and make good use of talented people, many ambitious people felt that it was a good opportunity and wanted to advance their careers.

As the Emperor's only son, Prince Tu Yuan also knows how to work hard and make progress. The Emperor does not agree with the closed-door education of the Prince and often calls him to discuss the Prince's studies. Zhang Ying can see that the Emperor pays more attention to the education of the Prince that combines theory with practice.

With the return of scholars from various regions to their hometowns and the issuance of proclamations across the country, the new mathematics curriculum had basically spread throughout the Qing Dynasty by the end of the nineteenth year of the Kangxi Emperor's reign. The bookstores selling the new mathematics curriculum were very extensive. The money that had been used to sell toys to repair roads was now being used to supply books on the new mathematics curriculum.

Yinzhen also considered the demand for the new mathematics textbook. After all, the free distribution of the new mathematics textbook was only for students with official titles. There were also some people who needed it but did not have official titles, or those who had official titles but found the original set inconvenient to use. Therefore, Yinzhen specially ordered that the price of the new mathematics textbook be reduced by one-fifth compared to the price of the regular books, and the profit from this reduction would be made up by his private treasury.

Yinzhen's approach suited the tastes of scholars. Using money from his private treasury to facilitate learning for students across the country was exactly what scholars wanted.

Throughout history, there have been emperors who used funds from the national treasury to make up for insufficient funds in their private treasuries. Emperors like Yinzhen did use funds from their private treasuries, but they mostly did so when the national treasury was already short of money.

Although the national treasury doesn't have so much money that it can't be spent, it can still cover some expenses. Yinzhen's actions truly show his dedication to the country and its people, which is sure to move scholars.
