The Han Chinese people of Sichuan speak a unique form of Mandarin, which took shape during the area's repopulation under the Ming. The family of dialects is now spoken by about 120 million people, which would make it the 10th most spoken language in the world if counted separately. The area's warm damp climate long caused Chinese medicine to advocate spicy dishes; the native Sichuan pepper helped to form modern Sichuan cuisine, whose dishes—including Kung Pao chicken and mapo tofu—have become staples of Chinese cuisine around the world.
