Is 78500 10 the phone number of Quzhou or Longyou?

Hello! The differences between Quzhou telephones are as follows: 3. Starting with Quzhou downtown (including Kecheng District and Qujiang District), 2. Starting with Qujiang District, 4. Starting with Jiangshan City, 5. Starting with Changshan County, 6. Starting with Kaihua County and 7. Starting with Longyou County! If it is a big city, what's more, it starts with a full netcom phone and ends with a tietong phone! Tietong seems to have been acquired by China Mobile, but these products of Netcom Tietong can't be used in a small place in Quzhou!
