Two taboos prevalent among tribes are as follows:
(1) The red pen taboo in China: In China, writing names in red ink is a taboo steeped in deep cultural history. Red ink was historically used by judges to write the names of those condemned to death. The use of chicken blood was also a common practice. Since then, red ink is considered to be a bad omen as it symbolizes the fact that death is written for the person whose name you write.
(2) Eating beef in India: In India, eating beef is taboo in many communities, especially among Hindus who consider the cow sacred. The cow is revered in Hinduism and plays an integral role in ceremonial and religious rituals. Due to this, a large part of the Hindu society considers killing cows or consuming beef as disrespectful.
