Dear customer:

Thank you for your support to our company's work all along! In view of the adjustment of tax policies, the value-added tax rate has been changed from the previous 16% to 13%. Customers who previously had a contract with our company for a 16% tax rate invoice are requested to transfer their payment to our company's corporate account before March 26th, so that we can issue the 16% invoice to you before March 31st. If payment is not made, the tax rate for invoices issued after April 1st will be automatically changed to 13%, and our company will not bear the price difference. The tax reduction is a policy that benefits the people, and the enterprise's input, output, and tax rates will be reduced. There is no mention of product price reduction. Please have a rational understanding of national policies and mutual understanding!
