Huantai Finance always sends short messages to cancel the subscription.

Huantai Finance always sends short messages saying that the reason for unsubscribing is the national regulations. China's "Regulations on the Management of Communication Short Message Service" clearly requires that short message service providers and short message content providers should not send commercial short messages to users without their consent or request, so short message companies have to add unsubscribe tips, "reply TD unsubscribe" or "reply T unsubscribe".
