Zhang Dagu and his wife, after all, were of advanced age and their survival instincts weren't particularly strong. They passed away before Wang Yun graduated from college.
Both Zhang Dagu and Pan Juan mentioned wanting to attend Wang Yun's graduation ceremony before they died.
When this story spread, many relatives said that the elderly couple couldn't let go of their granddaughter Wang Yun and that they were very fond of her.
Zhang Yu knew that for the old couple, the numerous trips they took together weren't without fondness for Wang Yun, but they valued blood relations more.
They continuously called out for Wang Yun before passing, regretting that they couldn't attend her graduation ceremony.
Zhang Yu felt that a more likely possibility was that they missed the days when they could travel abroad every year.
Back then, they were genuinely happy, savoring delicious food, enjoying beautiful scenery, and drinking fine wine.
