Core Viewpoint - A lawsuit involving Jiangsu Electromechanical Research Institute against Zhongtianze Holdings has emerged from a controversial "1 yuan" transaction, potentially setting a significant precedent in the capital market [2][4]. Group 1: Lawsuit Details - Jiangsu Electromechanical Research Institute claims that Zhongtianze Holdings, while being the controlling shareholder of Helen Zhe, sold a subsidiary, Lianshuo Technology, for only 1 yuan, leading to significant financial losses [2][3]. - The lawsuit seeks 30 million yuan in compensation, highlighting that the total assets of Lianshuo Technology were valued at approximately 51.5 million yuan, with debts exceeding 133.5 million yuan [3][4]. - The case is notable as it involves allegations of misconduct by the controlling shareholder, who is accused of intentionally devaluing the subsidiary's assets before the sale [3][4]. Group 2: Background on Lianshuo Technology - Lianshuo Technology's operational issues began in 2020, with the controlling shareholder halting its operations and refusing to approve necessary expenditures, leading to a significant reduction in its asset value [2][3]. - By early 2021, Lianshuo Technology was reported to have a net asset value of 22.5 million yuan, which was planned to be sold for only 250,000 yuan [2][3]. Group 3: Implications for Bit Technology - The lawsuit has also brought attention to Bit Technology, another company controlled by the same individual, which faced issues with its IPO application and subsequently ceased operations due to 300 million yuan in uncollectible receivables [5][6]. - Bit Technology's IPO was initially accepted in May 2022 but was withdrawn, and the company faced severe financial difficulties shortly after, leading to a complete halt in operations by mid-2024 [6][8]. - The company's financial records indicate a troubling trend of increasing accounts receivable and declining collection rates, raising concerns about its financial health [12][14].
