Excuse me, I'd like to check the phone number of a stewardess of Hainan Airlines. How can I check it?

Customer service is not, nor is it a department. Why do you need a phone? Why not just ask? I gave it to you, otherwise ... last time on the plane, a passenger said to me, you don't have to tell me your phone number. Do you believe I will know when I get off the plane? I ignored him, and when I got off the plane, he found my phone. To tell the truth, we really don't like passengers asking for the phone like this. What they do is an insecure job, which makes them even more insecure.
