Dr. Jengdor is the only one to confirm the progress of the twin chimpanzees to maturity. This channel is a video that discusses the fascination of great apes (#gorilla、#chimpanzee、#orangutan) and enrichment.

Environmental enrichment is a measure to reduce mental and physical stress and lead a happy life from the standpoint of apes, not from the convenience and emotions of human beings.
