the ink box was a small utensil for holding ink, and it was also a traditional stationery for study in China. It was produced in Daoguang period of Qing Dynasty and prevailed in Guangxu and the Republic of China. It is lighter and more flexible than inkstone, and it can keep the ink smooth and black, so it was very popular at that time and became a necessary thing for literati before the case. Copper ink cartridges, which combine painting, calligraphy and sculpture, have profound cultural connotation and artistic charm, and are favored by many collectors.

The author collected two bronze ink cartridges carved during the Republic of China, both of which were used by cultural figures during the Anti-Japanese War. One was square, and the other was round with the seal script "Give me back my rivers and mountains" engraved on the lid, which reflected the attitude and determination of the people of China to the Anti-Japanese War at that time. "Give me back my rivers and mountains", from the national hero Yue Fei, expresses the sincere heart of the Chinese people to recover their land. After the "September 18th Incident" in 1931, the northeast fell, and the Chinese nation issued a roar of national salvation and resistance to Japan. Countless patriots plunged into the torrent of the war of resistance. At that time, Zhou Chengzhong, a Jiangsu scholar, collected and combined the words "Give me back my rivers and mountains" from the calligraphy tablet handed down by Yue Fei, and with Yue Fei's signature and stamp, copied it into an inscription of "Give me back my rivers and mountains" in Yue Fei's calligraphy, which was widely published. The spirit of loyalty to the country shines on the land of China, inspiring countless Chinese children to die in the national disaster. "Reading does not forget to save the country, and saving the country does not forget to read." This famous saying comes from Mr. Ma Xiangbo, the first president of Fudan University (the predecessor of Fudan University). In a graduation speech, he made a generous speech, encouraging students to study hard and serve the country.
