Baidu's "receipt mail inquiry" can be inquired by entering the registered letter number on the pop-up page, and the results are as follows:

XH54972068 13 1 There is no corresponding information for this email. Please check whether the email code is wrong!

It may be that the registered letter just sent has not been scanned into the system by the postal staff, so the progress information can not be found for the time being. The results should be available tomorrow and the day after tomorrow, which can be found in Baidu's "email inquiry system".
