At symbol names in other languages

In mainland China, when used as a verb (eg.: @ somebody on twitter/x), we use "艾特" now and a few people use "圈" or "圈儿"(quānr) which is an abbreviation of "圈(儿)A".

I think the only scenarios when we need to read @ is as a verb or read an e-mail address. When reading e-mail address, I think most people just read it as "at" because other parts contain letters or English words anyway. But "." is pronounced "点[儿]"(dian[r]) rather than "dot".
