The Sweet Dew incident ("Ganlu incident", or ) was an incident on December 14, 835, in which Emperor Wenzong of the Chinese Tang dynasty, angry about the power that the eunuchs had, conspired with the chancellor Li Xun and the general Zheng Zhu to slaughter the eunuchs. The plot failed, however, when the eunuchs realized what was happening and counterattacked with soldiers under their command. Li Xun, Zheng, as well as many of their associates and other officials were slaughtered, and thereafter, the eunuchs had an even firmer control over Emperor Wenzong and his government than before.
