How about a license plate with a mantissa of 876?

Very good, 8- 7- 6- made a fortune and got a promotion. Smooth is the best 3 consecutive numbers within 10, and the first 8 ends with 6, which is very good and very lucky!

If these 2.6 million numbers are full again, there are two ways to continue numbering. One is to put English letters in the second place, from 0A000 to 0A999, then from 1A000 to 1A999, and so on to 9Z999. The second is that the first two digits are in English letters, from AA000 to AA999, and then to AB000-AB999.

And so on to AZ999, starting from BA000-BA999 and BB000-BB999, and extending all the way to ZZ999. If this number is still full, then put the English letters in the third place, such as Hangzhou, ranking from 00A00 to 99Z99. Then put the fourth and fifth letters in English, or continue to arrange them according to the first and third letters, the first and fourth letters and so on. Guangzhou recently ranked second and third.
