However, just for future reference, what you're looking for is called a proxy service! Basically someone that can communicate in both languages and is your middleman, doing the buying and communicating on your behalf. The thing about sites like that is that they require real ID verification and generally a chinese phone number, and proxies handle all of that on your behalf.
There used to be several dedicates accounts on Twitter for buying stuff on Mihuashi (the site the form is on). I believe the only one left that still does so is JingAtelier, but they do not accept orders under $100. There's also some dedicated communities on reddit that like to help foreign shoppers.
