Mr. Cheng will then provide details on the company's operating and financial results for the period before, and we open the call up for your questions. Before we continue, I would like to refer you to our State Harbor Statement in our earnings press release. Today's call will include forward-looking statements. These statements include, but not limited to, our outlook for the company, statements and estimates, and project future results of operations, or the performance of the company. These statements speak only as of the date hereof, and the company assumes no obligation to revise any forward-looking statements that may be made in today's press release call, or webcast, except as required by law. These statements do not guarantee future performance and are subject to risk, uncertainties, and assumptions. These report to the press release and the risk factors and documents we file with Securities and Exchange Commission, including our most recent annual report on Form 20-F for information on risk, uncertainties, and assumptions that may cause actual results to differ materially from those set forth in such statements. In addition, during today's call and webcast, we will discuss both GAAP financial measures and certain non-GAAP financial measures, which we believe are useful as supplemental measures of the company's performance. These non-GAAP measures should be considered in addition to and not as a substitute or in isolation for GAP results.

You can find additional resources regarding GAP measures, including a great compilation of comparable GAP methods and GAP results in our learning series, which is posted on the company's website. With that, I would now like to call over to our chairman and CEO, Ms. Anna Tuchel.
