Shen Jingqi mentioned the HL's Rhesus Monkey experiment.
According to the research by HL, a psychologist from M Country, and his colleagues, newborn monkeys spend six months with two mothers. The iron-wire mother holds a milk bottle, while the cloth mother wears soft clothing. The infant monkeys only go to the iron-wire mother for milk when they are extremely hungry, and at other times, they prefer to stay with the cloth mother. Moreover, when the infant monkeys encounter danger, like the threat of a large wooden spider, they run to the cloth mother and cling tightly to her. The experiment concluded that physical contact plays a role in the development of the infant monkeys that even surpasses the role of food. Particularly, the warmth provided by the cloth mother is what the infant monkeys long for.
This warm touch is a necessity of life.
"Warm touch~!"
Li Baiyu said slowly.
"Yes."
