In ancient China, kitchens were considered the heart of the home, and some featured built-in indoor living walls adorned with lush greenery. These living walls not only added a touch of natural beauty to the kitchen but also had practical benefits. The plants helped to purify the air by absorbing pollutants and releasing oxygen, creating a healthier cooking environment. Chinese cuisine has always emphasized the use of fresh ingredients, and the incorporation of an indoor living wall in the kitchen was a way to ensure a constant supply of herbs and greens for cooking. It also added a sense of harmony and balance to the space.
