Dear David, I hope this letter finds you well and your travels in China have been truly enriching. I'm writing with a heavy heart to express my sincere apologies for not being able to see you off at the airport this Saturday as we had previously planned. Regrettably, an unforeseen emergency has arisen at the last minute, which requires my immediate attention and prevents me from being able to fulfill my commitment. It's a matter that cannot be postponed and demands my personal presence. I understand how much significance our goodbyes hold, and I am truly saddened that I won't be able to share that moment with you in person. Please know that my thoughts are with you as you embark on your journey back to the UK. I hope the memories we've made during your stay here will accompany you on your flight and in the days ahead. Rest assured, our friendship transcends physical distances, and I look forward to hearing all about your adventures and reflections once you're safely home. Once again, please accept my deepest apologies for any inconvenience caused. Keep in touch, and let's make plans to catch up soon, perhaps over a virtual cup of tea or on your next visit to China. Safe travels, David! Warmest regards, Li Hua
