Shenshu and Yulü

Shenshu or Shentu (Chinese: 神荼) and Yulü or Yulei (simplified Chinese: 郁垒; traditional Chinese: 鬱壘) are a pair of deities in Chinese mythology who punished evil spirits by binding them in reed ropes and feeding them to tigers. Their images together with reed rope seasonally adorned the doors or gates to ward off evil, and are considered the earliest examples of Menshen (門神, 'gate deities' or 'door gods') venerated under such practice. Later traditions identified other gods or deified people as gate deities.

The description dates to writings from the 1st and 2nd centuries AD, during the Eastern Han dynasty, and the attribution to the Classic of Mountains and Seas dating much earlier appears to be spurious.
