I came from China and use this software for sometimes. It is good but I find it is hard to donations for this software.
PayPal did not support Chinese credit card. It is easy to pay by Wechat pay or Alipay for chinese.
So please consider to add this channel to donations.
And as the ETH & USDC/T were the most popular Crypto ,please add eth wallet address.

Thanks for the suggestions.
We are looking into more ways to accept donations.
