《旧唐书·列传·卷八十五》
王叔文刚进入翰林院，从苏州司功参军升任起居郎，不久就兼任度支、盐铁副使，任命杜佑为使，实际上王叔文掌权。
叔文初入翰林，自苏州司功为起居郎，俄兼充度支、盐铁副使，以杜佑领使，其实成于叔文。
Not long after Wang Shuweng entered Hanlin Academy, he was promoted from the participating military counselor of Suzhou to the imperial attendant. Soon, he concurrently assumed the post of deputy envoy for finance and taxation, with Du You appointed as envoy; however, Wang Shuweng was the one who actually held the power.
