永定河上游桑干河灌区是山西省大型自流灌区之一。

Sangganhe irrigation district on the upper reaches of Yongdinghe River is one of large-scale artesian irrigation districts in Shanxi province.

山西北部由海河的支流流过，例如桑干河和滹沱河。

The north of the province is drained by tributaries of the Hai River, such as Sanggan and Hutuo rivers.

此后，丁玲端正态度，创作出被领导人认可的《太阳照在桑干河上》而受到表扬。

Afterwards, she corrected her attitude and created the novel "Sun Ray on the Sanggan River", which was approved and praised by the leaders.
