What does Zhang Yuxing Shield mean?

It is the name of a wine under Changyu brand.

Yantai Changyu Group Co., Ltd, formerly known as Yantai Changyu Brewing Company, is the first industrialized wine producer in China founded by Mr. Zhang Bishi, a patriotic overseas Chinese leader in modern China. 1892, Zhang Bishi invested 3 million taels of silver to establish Changyu Brewing Company in Yantai. Li Hongzhang, governor of Zhili in the Qing Dynasty, minister of Beiyang, and Wang Wenshao, an important official of the Qing court, personally signed and approved the company's business license, and Weng Tong, the teacher of Emperor Guangxu, then minister of civil affairs and minister of military aircraft, wrote the company's name in his own hand. The word "Changyu", surnamed Zhang, means prosperity. The establishment of Changyu Company was recorded by Beijing China Millennium Monument as one of the four major events in China in 1892. Now it has developed into a diversified group enterprise and is the largest wine producer in China and even Asia.
