The "Lao Yusheng" firm founded by Zhang Gong, the 14th ancestor, opened the domestic coastal market in the eastern part of Jiangsu and Shanghai with the help of the "red-headed ship" in Zhang Lin, so it is widely rumored that "the preserved vegetables in Gaotang are branded with porcupines' tongues".

1820 (Jiaqing period of Qing dynasty), the 15th ancestor opened Gong Wei to carry forward the name of "Old Yusheng", made "Golden Rooster" preserved vegetables, packed them in wooden barrels with bamboo leaves, and shipped them to Siam (Thailand). It is said that each batch of shipments can reach 150 tons, and "eating preserved vegetables and thinking about home" has become the yearning and sustenance for the relatives in Tangshan.
