Marquis of Extended Grace

Koxinga's grandson Zheng Keshuang surrendered to the Qing dynasty in 1683 and was rewarded by the Kangxi Emperor with the title "Duke of Hanjun" (漢軍公).

In contrast to the practices of previous dynasties, the marquis served the Qing monarchy as subjects, instead of honoured guests with independent fiefdoms.

In September 1924, Zhu met Reginald Johnston, the British tutor of Puyi, the last Qing emperor.

"[15] The business card Zhu gave Johnston said he was a descendant of the Ming imperial family and lived in Yangguan Alley, a hutong near Dongzhimen.

[16] After Puyi was evicted from the Forbidden City in the Beijing Coup in October, Zhu visited him at the Japanese concession in Tianjin.

In 1929, Zhu Yuxun petitioned the National Government of the Republic of China for help since he was living in destitution and said he could no longer carry out his duties.
