What is the formal/polite way to begin and end an email in Chinese? In English, formal emails, e.g. emails to a professor, often start with &quot;Hi&quot;, &quot;Hello&quot;, &quot;Dear&quot; followed by the receiver's name (and title, if applicable). The ending is usually &quot;Best&quot;, &quot;Regards&quot;, &quot;Sincerely&quot; followed by the writer's name. Does Chinese have similar constructs? Or does it have more/less strict rules?
The traditional Chinese letter is very complex.It has many honorifics that vary greatly for different receivers.

But today,most people's traditional education is insufficient to write these letter.

For email,people tend to write simply and practicably。

Habitual formation。
