Why is the telephone number in the public security bureau of each province 110? I am from Jiangxi and I am in Beijing. Why are the police numbers in Jiangxi and Beijing both 110?

110 will take you to the nearest public security bureau, regardless of province or city, it is the same across the country. If you take the test with a mobile phone from Jiangxi and bring it to Beijing, your mobile phone will automatically recognize the Beijing area roaming, and you If you use your hand to dial a Beijing landline in Beijing, you will find that there is no need to add the area code in front of the number. Do you understand this explanation? As for calling 110 from a landline, there’s no need to explain, right?
