In ancient times, Fujian is very special, all around are mountains, traffic is very underdeveloped, Fujian Province's mountainous hilly area accounts for about 90% of the province's total land area, so far Fujian is China's highest forest coverage province. Moreover, this place in Fujian was very closed before, until the Yingxia Railway, which was completed and opened to traffic in 1957, and the talents inside and outside were able to move around and communicate with each other, and then slowly changed this situation. Just by virtue of the railway, we can see what kind of a place it was in ancient Fujian.
And there are many clan forces in Fujian, and every village is a clan. In order to compete for resources, it is common for major clans to fight each other. This also cultivated the ancient Fujian folk style, but once there is a foreign invasion, everyone in Fujian will be unanimous.
The unique terrain coupled with the unique folk customs made this place a place that the imperial court did not dare to manage. From ancient times to the present, no matter which dynasty, it has wanted to completely control this part of Fujian, but it has ended in failure.
Until modern times, the War of Resistance Against Japanese Aggression occurred, and Japan occupied many areas. This place in Fujian, the Japanese have come, at a glance, basically all mountains of Fujian, so that the Japanese are very headache. I could only try to attack, but all of them were driven out by the Fujianese. Subsequently, the Japanese army tried to attack by water routes, doing small-scale operations in the coastal areas of Fujian and the hinterland, although it also successfully captured some ports, but it could not expand the results of the battle to a greater extent.
Japan also sent spies to operate in the Fujian region, hoping to find a breakthrough. Soon, a word came from the spy: In Fujian, the people are not afraid of threats, and bringing them to their knees with majesty will inevitably lead to resistance.
The troops in other areas were tight, and the Japanese were very entangled in the long-term inability to conquer Fujian. After thinking about it for a long time, I came to the conclusion that if I wanted to take Fujian, I had to gather all the Japanese soldiers to hope to do it. But this was obviously an impossible thing, and Japan finally made a decision to abandon Fujian and withdraw its troops from Fujian. Even if it was a port that was hard to conquer, it was all returned to Fujian.
