I Agree with you @shri
HK is surely not a good place for me at this moment. I have tried all the solutions (both conventional and unconventional) but didn't succeed. Thank you so much for your generous support and smart advices. I promise, wherever I am, I will try to be a better person and a helpful person.
I will always remember the people (like you) who had given me a helping hand in HK and I will always feel grateful by remembering the gratitude.
I am sincerely sorry for any inconvenience it may have caused.
I did send the msg. It might be the misunderstanding between us due to the technical failure.
The technical failure usually occurs during the late evening. When it happened, the website will automatically logout by itself. I might have sent the msg on the time of auto-logout by the geoexpat site.
I have used some of the helpful advice and have worked/working on them. All's help is noted with thanks and hard work.
Thank you so much for your concern. Have a beautiful day!
