"It's a hot day, cold water is fine for washing." Heating water consumes so much firewood and energy.
However, Meng Yunhan thought differently, "Dad, you might not feel anything now as you're young, but as you age, you'll start experiencing all sorts of conditions like arthritis. For Xiaohu and me, you should aim to live another few decades. By then, you'll still be around to see Xiaohu get married and hold your great-grandchildren."
Old man Zhao's face lit up with joy, "Alright, I will strive to live a few more decades to hold my great-grandchildren."
Meng Yunhan was bathing Xiaohu, washing his tiny bottom. Due to the hot weather, Meng Yunhan worried that Xiaohu would overheat. Each time, she would wipe their bodies down with warm water.
Once she finished washing Xiaohu, she let him play on the bed.
