蛋 is not an ancient picture of an egg. Historical dictionaries connect it with the older character 蜑, and its use for “egg” developed over time. The modern form places 疋 above 虫, but reading those parts as a literal story about an egg would be folk etymology. Because no secure oracle-bone egg picture stands behind this everyday form, the sketch is a seal-form-inspired guide to its components, not a reconstruction.
A piece of culture
Red eggs for a new beginning In some Chinese communities, red-dyed eggs are shared to celebrate a baby’s first month or another happy family occasion. Customs differ by region and family, but the round egg can suggest wholeness and new life, while red is widely associated with good fortune and celebration.
