transwiser is now integrated at the dacplay webwallet,below is the UI:
in deposit pop window, user can click the link or scan the QR to the webpage in weidian.com to buy BitCNY, the page is in chinese, and you can pay when you have an alipay account or a CNY bank account.
withdraw is a little easier, but you also need an alipay account, input the withdraw amount and your alipay account and click "withdraw", your BitCNY will be sent accordingly and you will receive CNY in your alipay account.
thanks for boombastic to develop this, he will submit the pull request later, hope everyone enjoy this.
