Dear Liu,

I trust this email finds you in good health. I want to express my gratitude for your kind invitation.

Currently, attending classes in person or in a blended format is a challenge for me. Therefore, I kindly request your assistance in arranging an online class for me, if possible.

I eagerly await your response.

Thank you once again for your understanding and support.

Best Regards,

Jian
