公行雖然係有民間自發嘅性質，但有著官府嘅背書支持，清廷官府係樂於有咁嘅組織，作為中間機構同外商打交道，仲代埋官府徵收啲關稅。有咗官府嘅支持，公行就壟斷埋貿易，而多次引起其他商人同外商嘅反對，第一次建立嘅公行好快就喺1721年解散咗。但到咗1760年公行有恢復返，直至1771年再俾人解散，跟著喺1782年又出返來，一直做到大清喺鴉片戰爭打敗仗後簽訂《南京條約》（1842年）先至俾廢除。
Although the public bank is spontaneous in nature, it has the endorsement and support of the government, and the Qing government is happy to have this kind of organization, acting as an intermediary and dealing with foreign businessmen, and also collecting some tariffs on behalf of the government. With the support of the government, the public bank monopolized trade, which repeatedly aroused opposition from other merchants and foreign merchants, and the first public bank was soon dissolved in 1721. However, by 1760 the public bank had been restored, and it was not dissolved again in 1771, followed by the Treaty of Nanking (1842), which was abolished in 1782 after the defeat of the Opium War.
