What achievements did Su Xiang, the prime minister of the Tang Dynasty, achieve?

In 702 (the second year of Chang 'an), Su Xiang was ordered to review the cases handled by Lai Junchen and other cruel officials, so as to avenge the wrongs.

In 7 16 (the fourth year of kaiyuan), Su Xiang was promoted to assistant minister Wei Zi, became prime minister with Wei Zihuang, and jointly ruled with Song Jing. Song Jing was an upright man who made decisive decisions on many government affairs, while Su Xiang obeyed his beauty. When playing in front of the emperor, if Song Jing didn't expect or couldn't answer at the moment, Su Xian would come forward to help.

In 7 18 (the sixth year of kaiyuan), Emperor Xuanzong of the Tang Dynasty issued a decree prohibiting the circulation of evil money, confiscating folk money and things, and melting them into money, which made the hearts of the capital float and all transactions almost stopped. Su Xiang and Song Jing went to the imperial court and suggested that the imperial court take out 20,000 yuan to buy the unsalable goods in the hands of the people at a low price for the use of the imperial court, and allow Beijing and Beijing officials to advance their official salaries so that good money can flow into the people.

In 720 (the eighth year of Kaiyuan), Su Xiang was dismissed as the minister of rites, and soon became the prefect of Yizhou, inspecting Jiannan states. At that time, Shu was depressed and the people were displaced. After Su Xiang came to power, he recruited troops, dug salt wells, smelted iron, made money from salt and iron, bought grain and enriched the grain depot.
