On April 14, 2026, Zhu Lei, the Chief Marketing Officer (CMO) of Gree Electric Appliances, posted on social media that Hisense air conditioners were observed to directly adopt Gree's original promotional tagline, "Genuine Copper, Genuine Materials," at the Shanghai Home Appliances Expo. Zhu Lei underscored that this tagline transcends mere wording; it represents a comprehensive set of quality standards. He argued that as long as products incorporate aluminum-wire motors, the brand lacks the credibility to label itself as adhering to "Genuine Copper, Genuine Materials."
