Since few people want to live on the “death” floor, many apartment buildings throughout East Asia omit floor four.

The Haenyeo (women of the sea) are a group of several thousand women living on the South Korean island of Cheng, engaged in seafood fishing in the Yellow Sea. Haenyeo women hunt for octopus, sea urchins, and sea snails by diving to depths of 20-30 m without air cylinders, and equipped only with fins, goggles, and gloves. Dives last 2-3 min, and are performed for 5-7 h, which allows catching about 30 kg of seafood. The average age of Haenyeo women is 60 years, with 98% being over 50 years old. Haenyeo has been listed as a UNESCO intangible cultural heritage. ⁴⁾
