Which province did the 12th Ring Road in Beijing go to?

There is no twelfth ring road in Beijing.

There are no twelve rings in Beijing, only seven rings, and the outermost ring is the seventh ring road in Beijing. The so-called "Twelve Rings in Beijing" is just a joke circulated by some media or the Internet, but it does not exist. Therefore, it has no practical significance to ask "which province did the 12th Ring Road in Beijing go to?".

Beijing generally refers to Beijing, referred to as "Beijing" for short, and was called Yanjing and Peiping in ancient times. It is the capital, municipality directly under the Central Government, national central city and megacity of People's Republic of China (PRC), and the political center of China determined by the State Council.
