: In the scientific paper presented at the International symposium on Geodetic Net- works and Computations of the IAG held in Munich, Aug, 31-sept. 5. 1981, the author had given a brief introduction to the adjustment of astro-geodetic network of the peop- le's Republic of China. This paper is an extension of the former one. The adjustment had been completed thoroughly in May. 1982 with satisfactory results. This paper des- cribes the mathematical principle of the method of adding constant used in the adjust- ment for solving linear equations, the accuracy requirement on the formulae, the method for examining large quantities of observed data, the assignment of weights to various observations, and the measures adopted for solving technical problems occurring during the adjustment. Also included are the final results of the adjustment.
