There will be deserters in any country under any circumstances.
Survival is human instinct, and it is easier to have the consciousness of subjective escape when the battlefield situation is unfavorable.
Some deserters just fled the battlefield, and some simply fled home.
But what awaits them will be severe legal punishment.
So some Japanese deserters did not return to China and married and had children with the locals. A few days ago, they spread to the Philippines and found the veterans of that year.
Many people have also stayed in China, and now Japanese relatives often come to China to recognize their ancestors and return to their ancestral home.
