Etiquette introduction of texting

For elders and venerable ones, it is not appropriate to send messages to celebrate the New Year. Instead, you should go to your home in person or call them to say hello. The closest friends want to edit their own content when they use text messages to celebrate the New Year, and text messages are also taboo to be sent everywhere like gifts. Some simple work communication between colleagues can be carried out by SMS, but subordinates can't talk to their superiors by SMS unless their superiors ask for it or get their consent in advance.

For some important appointments, it is more polite to gently remind each other by SMS than to confirm them by phone many times. However, it should be noted that you must invite or confirm by phone or in person before sending SMS. When forwarding short messages, we must pay special attention to the content of short messages. Those absurd, unhealthy and mischievous short messages must be sent carefully.
