The Bigan Temple in Weihui, north of Xinxiang city, marks the tomb of the Shang-dynasty official Bigan, who died around 1100 BCE after repeatedly opposing the tyrannical behaviour of King Zhou Xin. Bigan's story became one of the central moral exemplars in Chinese political culture — the loyal minister who speaks truth to a ruler even knowing it will cost him his life — and the site has been a pilgrimage destination for over three thousand years. The current temple complex dates to the Han dynasty, though it has been reconstructed many times, and includes memorial halls, carved stelae, and the ancient tomb mound surrounded by trees.
The most striking feature of the temple is the ancient Chinese hackberry tree said to have grown from the spot where Bigan's heart fell to earth. The Lin family, one of several lineages that claim descent from Bigan's scattered household, holds a major ancestral ceremony here every year that draws participants from across China, Taiwan, and Southeast Asia. The site is also significant to branches of the Lee and Lin families who trace their lineage to Bigan — making it one of the most visited genealogical pilgrimage sites in Henan.
