The frequency of meetings between Musk and Zeng Yuqun, chairman of the Chinese battery giant Ningde Era, became a yearly date. According to Reuters, Zeng Yuqun, chairman of the Ningde Era, visited the hotel where Musk was staying in Beijing on Monday. The Tesla CEO arrived in Beijing a day ago for an unannounced visit. Ningde Times is Tesla's main battery supplier. According to eyewitnesses, Zeng Yuqun came out of the elevator and shook hands with two Tesla Chinese executives waiting in the lobby. According to industry insiders, due to the recent sudden resignation of Drew Baglino (Drew Baglino), senior vice president of Tesla's powertrain and energy business, the self-production process of the 4680 battery that Musk had high hopes for may have suffered an unprecedented blow. Furthermore, according to the quarterly report released by Tesla, its profits have declined sharply. Based on the above situation, Musk met Zeng Yuqun again this time and may seek more help with 4680 batteries and cheaper power battery supplies. (Exciting)
