Which province are the ancient Khitan, Nuzhen, Liao and Jin?

The Khitan State is actually the Liao State, which is also called the Khitan State because it was founded by the Khitan nationality. Jurchen State is actually the Jin State, which is also called Jurchen State because it was founded by Jurchen people. However, the country founded by Jurchen and the later Jin Dynasty were also in the Qing Dynasty, and you should be asking about the territory of the Song Dynasty.

The heyday of the Jin Dynasty should be from Xizong to Sejong, with a land area of 3.61 million square kilometers (1142 years), reaching the Huaihe River in Qinling Mountains in the south, Qin 'an in Longxi in the west and Liupan Mountain in the east, the eastern slope of Daxing 'anling in the north and the upper reaches of Heilongjiang River in the east, and the Songhua River in the east and the mouth of amur river in the Russian Far East bordering tatar strait today. That is, today's three northeastern provinces, Hebei, Henan, Shandong, Shanxi and parts of Anhui and Hubei.

At the heyday of the Liao Dynasty, the territory reached Sakhalin Island in the northeast, Selenger River and Shileka River in central Mongolia in the north, Altai Mountain in the west, Haihe River in Tianjin, Baxian County in Hebei Province and Yanmenguan in Shanxi Province in the south. The land area is 4.89 million square kilometers (in 1111), which is the three northeastern provinces, Inner Mongolia, Shanxi, Hebei and some areas north of the Yellow River.
