Jiang Changhai saw his daughter-in-law picking up bowls and hurried over to take them from her. In front of everyone, he earnestly said, "My dear, you've just started your period. You shouldn't touch cold water. Just sit down and rest."
"Well then, my back is really aching." Although Su Wanyu wasn't actually in her confinement period, she immediately feigned being very weak and sat down on the stool, holding her back.
Jiang Changhai had indeed said this for the benefit of the other people in the room, to save Su Wanyu from talk that she was being lazy and avoiding work.
Jiang Changhai and Su Wanyu were recognized by Zhang Guihua as the laziest of the lot, but considering the eldest had not spared any expense or effort for the longevity feast, she did not discredit them and allowed it pass.
Being one of Jiang Family's daughters-in-law as well, Sun Lixia couldn't help but feel a bit jealous. The eldest really treated his sister-in-law well!
