How should he understand this sentence? "Isn't it generous to let future generations be called the descendants of innocent officials?"

Yang Zhen word Bo Qi, Hongnong Huayin people. When he was young, he was studious and read extensively. The Confucian scholars said: Kansai Confucius Yang Boqi. General Deng Zhi heard that he was virtuous and recruited him, recommended him as Mao Cai, promoted four times to Jingzhou governor, Donglai prefect. When he went to the county, he passed Changyi on the way. Wang Mi, the former recommended Jingzhou Maocai, was appointed Changyi County Magistrate. He paid an audience with him. At night, he took ten catties of gold and gave it to Wang Zhen. "What is the reason," said Zhen,"that an old friend knows you, but you do not know an old friend?" "He who knows nothing at night," said Li Mi. "Heaven knows, God knows, I know, you know. What is ignorance!" Li Mi was ashamed and went out. Later, he was transferred to the prefect of Zhuo County. He is honest and does not accept private visits. His descendants often ate vegetables and walked on foot. Some old elders wanted him to open up a business for them, but he refused."Isn't it generous to let future generations call him the descendants of innocent officials?" he said. The questions were as follows: The last sentence, after checking the information and the introduction on the Internet, was mostly translated as "Let the descendants be called the descendants of honest officials. Wouldn't it be very generous to give this to them?" Here, the word "Shi" was interpreted as "Rang", and "Ci" referred to the good name of "the descendants of innocent officials". But I have another idea. The sentence is interpreted as: "If future generations are called the descendants of innocent officials, and I leave these industries to them, isn't it too much?" Here, I interpret the word "make" as "if","this" refers to "industry"(see above), and "thick" means more. Is this explanation okay? Please enlighten me if you understand!
