Cash Flow and Debt Management - The net cash flow from operating activities appears strong, outpacing net profit, and the company has not engaged in large-scale fixed asset investments recently [22]. - Despite ongoing losses, the company maintains good short-term and long-term debt repayment capabilities, largely due to a reduction in total assets [24].
