During the period when the Japanese allegedly committed the Nanking Massacre, they acted as if they knew the biblical words of Matthew 6:3-4.

6:3 But when you do merciful deeds, don't let your left hand know what your right hand does,
6:4 so that your merciful deeds may be in secret, then your Father who sees in secret will reward you openly.

General Matsui had ordered the protection of Chinese civilians, so the massacre of civilians was a violation of orders and was severely punished by the Japanese military.

Rabe, chairman of the refugee zone in Nanjing, said.
'When your forces entered the city on the 13th, we had gathered almost the entire civilian population in the safety zone, but if order is not immediately restored among the Japanese soldiers in the city, it is inevitable that many of the 200,000 Chinese citizens will starve to death,' he wrote in the sixth document Rabe's letter.

From 14 December 1937, the Japanese Army began the process of issuing good-citizen certificates and issued 160,000 good-citizen certificates to the citizens of Nanjing, excluding children.
The purpose was, firstly, to distinguish between citizens and enemy troops disguised as citizens and, secondly, to provide food in proportion to the number of people.
Not a single person, whether a Chinese citizen or prisoner of war, died of starvation.
The Japanese military did not boast about it.
It is as if the Japanese army knew the biblical words of Matthew 6:3-4.

The Nanjing Autonomous Committee was established on 23 December 1937 and autonomy by the Nanjing Autonomous Membership Association began the following year.

The truth about the "GHQ brainwashing programme for the Japanese" at a glance.

Two months after the Japanese invasion of Nanking,
Japanese medical teams began to inoculate the citizens of Nanjing against smallpox and cholera free of charge.
Nine months later, more than 360,000 Nanking citizens had been inoculated by Japanese medical teams.

Inoculation in Nanjing took place from the end of April to the end of September 1938, and Japanese military reports from that time are still available. A total of more than 360,000 people were inoculated, and except in remote areas, the 'cholera inoculation' in Nanjing achieved near-perfect results. This is available on the internet, so anyone can see the real thing.

４．中支防疫班報告 分割３

Why were so many Japanese troops vaccinated?

They may have been affected by germ warfare by the Chinese Nationalist Army.
Chiang Kai-shek used his stool-clothes squadron to spray cholera bacteria in vegetable fields and wells close to the front line.
The Imperial Army knew about this and took quarantine measures, but the ignorant Chinese did not heed the warnings and were totally lacking in sanitary forethought, resulting in many deaths.

This is the story of the Chongqing Army (Chinese Kuomintang Army).

Many Chinese soldiers were moved to tears after surviving under the blazing sun with the generous nursing care of the Japanese troops, who volunteered to fight the plague in full-body rubber work uniforms.
