Why is it a joke for mothers to help the "wounded"? What happened?

A famous fake photo appeared in the 1980s, manipulating a young mother to learn the "red sister-in-law" of Yimeng Mountain during the Anti-Japanese War on the front line of Laoshan, to quench the thirst of the "wounded" on the battlefield. In the 1980s, she was called "Red Sister-in-law", and the new version of Yimeng Fu is still a joke. This famous "fake photo" 20 years ago was provided by the late photojournalist Jiang Qisheng and exhibited in the exhibition "Difficult Journey".

Truth: The photo was posed. In the photo, the word "Qian Qian" can be clearly seen on the armband of the woman's right arm. Where is the soldier's sign? 100% people. Also, anyone who has been a mother will experience it. If it's not a posed photo, is it necessary for a woman to dress up as a militia to breast-feed her on such an exaggerated scale?
