write an English email to TC68 秘书邮件要包括主题邮件内容是告知秘书：由于行程原因冯蕾无法去悉尼现场参加年会她会远程参会语气平常 不要啰嗦 开头寒暄

Dear TC68 Secretary,

I hope this email finds you well. I am writing to inform you that due to some unexpected changes in her travel plans, Feng Lei will not be able to attend the annual meeting in Sydney in person. However, she will be participating remotely.

Thank you for understanding the situation and please let us know if there are any further arrangements that we need to make for her remote participation.

Best regards,

[Your Name]
