LINGVIST should also have many users in mainland China, but only support foreign credit card strategy makes it difficult for many users to pay. So I hope to support Alipay or WeChat payment to facilitate user subscription. At the same time, the software pricing is too high for users in mainland China, hoping to increase some preferential policies to increase the payment rate. For example, Steam is much cheaper in the renminbi-settled area than the U.S. dollar, but having a large number of paid users can also generate enough revenue.
