1 If you want to reach a fix-lined phone number, you could directly dial the number. But if the phone number belongs to another city of the same province, an area code should be added before the phone number. For example, if you are in Fuzhou, Fujian, and you want to make a phone call to  Fuzhou, Fujian, “0591” should be added before the phone number. And if you dial a number of another province in China, an area code should also be added before the phone number. For example, if you are now in Beijing, and you want to call a phone in Shanghai, “021” should be added before the phone number.
2. If you want to reach a mobile phone number in the city, you could directly dial the mobile number.

For example, you are now in Shanghai and you want to dial a mobile phone number in Beijing, you should dial 013609596500.
