Yibing shan email header

I'm assuming you're referring to Yibing Shan, a Chinese-American mathematician and professor. Here's an example of an email header for him:

Subject: [Your Subject Line]

From: [Your Name] [Your Email Address]

To: yibing.shan@[University/Institution]

CC: [Optional CC Recipients]

Date: [Current Date]

Here's a breakdown of the components:

• Subject: A brief summary of the email's content.
• From: Your name and email address.
• To: Yibing Shan's email address at his university or institution.
• CC: Optional carbon copy recipients, if you want to keep others informed about the email.
• Date: The current date, which is automatically added by most email clients.

Please note that you should use a professional tone and format when sending an email to a professor or academic.
