什么问题该说什么What to include
算法口径有疑问A question about the methodology
如果你算出来的结果和实际账单对不上，把标价、实际扣款、消费日期和币种告诉我们。费率是你自己填的，差异往往出在某一层费用被漏掉或重复计算。
If a result does not match your actual statement, send the price, the amount charged, the date and the currencies. All rates are user-entered, and the gap is usually one fee layer either missed or counted twice.
想支持更多货币或卡组Another currency or network
说明你需要哪个货币、哪个卡组织，以及你所在的常用场景。
Tell us which currency or network you need and the situation you use it in.
攻略内容有误Something in a guide is wrong
指出哪一篇、哪一段，以及你的依据。费率和规则会随银行政策变化，发现过时内容欢迎告诉我们。
Point to the guide and the passage, with your source. Fees and rules change as banks update their policies, so corrections on outdated content are welcome.
合作Partnerships
内容合作、工具嵌入等，邮件说明来意即可。
Content collaboration, embedding the calculator elsewhere — just say what you have in mind.
