The company rewards travel abroad. Where can I not fly? Will I check my cell phone?

There are many things that are not allowed on the plane, such as liquids, including liquid water, masks and lotions. Secondly, it includes some high-power appliances, such as high-power charging treasure; Third, some dangerous goods such as lighters. Finally, for example, some dangerous goods, such as controlled knives. So all the above things must be cleaned up before boarding the plane, otherwise they will be taken away or let you check in when passing the security check, which is more troublesome. Finally, I said that the mobile phone must not be checked.
