sentences:  Under the "Zhece policy" Chinese merchants were paid in salt certificates for supplying the military of the Tang dynasty directly as opposed to merely transporting government provisions to them.During the reign of the Emperor Xianzong the supply of cash coins in circulation was scarce and when Chinese merchants would travel to the capital city, the merchants would entrust their money to the representative offices of their local governments, to the various armies of the Tang dynasty, government commissioners, and local rich families.The merchants did this to lighten their traveling burdens as they would hurry away in all directions.
