Unlike the much exaggerated Sati, the Chinese Xunjie or Widow Suicide system killed lakhs of women.
Widows were forced to starve themselves to death or poisoned so they didn't have sex after the husband's death. The Chinese society built thousands of arches (called Paifamg) to glorify the practice.
But literally nobody even knows about it today because information & media are frauds. Hence we must share it.
