These nuns were hidden in straw by Qiao Zhiyong, escorted out of Shanxi, and finally rescued and returned to Italy. In order to thank Qiao Zhiyong, the Italian gave him a national flag, and the jstars have been hanging at the door. When the Japanese invaded Shanxi, they saw the allied flag at the gate of Joe's compound. They were afraid of the Axis Italy and gave up the looting of the jstars.
In fact, just look at the deadlines of two things and you will know that this rumor is unreliable. 1937 Japan invaded Shanxi. Although Japan established allied relations with Germany in 1936, the Axis was established in 1940. In this case, it is absolutely impossible for the Japanese to take into account the so-called in 1937. Allies Italy? Face. Then why didn't they smash and rob the jstars' compound?
First of all, although Japan captured Shanxi, it is next to Shaanxi revolutionary base, and they still have concerns. At this time, what they have to do is to buy people's hearts quickly, draw in as many wealthy businessmen and traitors as possible, and be careful not to cause riots among the people in Shanxi. If the jstars hadn't left early, I'm afraid the Japanese would have won first.
Moreover, the Qiao family is a famous big family in Shanxi. Qiao Jiaping accumulated virtue and did good deeds, and also did a lot of good things for the people. If the Japanese army smashed the Qiao family compound, it would be ignoring the Shanxi people, which would easily arouse public anger. Tough measures are not enough, and the Japanese army has to adopt a policy of appeasement. After all, they don't want to stir up disputes at this time and cause unnecessary losses.
Another point is similar to the fact that the Japanese army did not destroy the Forbidden City. Japanese people are deeply influenced by China culture. On their own land, ancient Chinese-style buildings are well preserved. Japanese scholars are extremely opposed to the Japanese army smashing and looting ancient cultural books in China. So when they saw the magnificent buildings in China, the first reaction of the Japanese army was to surrender and admire them because of their own culture, and wanted to take them for themselves.
In the Japanese planning, these great buildings in China will all be their own in the future, and they don't have to have a hard time with their own property. When protecting the Forbidden City, the Japanese wanted to give the Japanese emperor a place to work and live in the future. It is not excluded that some senior Japanese officials have taken a fancy to the jstars compound and want to be there. Victory in invading China? After that, the whole family moved here. So they didn't do anything to the jstars courtyard. On the one hand, they are selfish; on the other hand, they are afraid of the resistance of the people of China.
