Shen Qiuhua packed many things for her daughter-in-law to bring home. When the Su family could not afford to eat in the past, Liu Yinyin was the one who brought back grain from her parent's house for the Su family to eat.
The Su family could only return the favor after the autumn harvest. Also, Liu Yinyin had taken her two children home when Su Wenzhe went to work at the Zhu residence.
Shen Qiuhua could not forget what her daughter-in-law had done for her family. She felt sad whenever she thought about that, but she could finally repay Liu Yinyin and her family for their kindness.
Liu Yinyin looked at everything her mother-in-law had packed and was thrilled. She wanted to save face when she returned to her parent's house instead of only going to them for help.
Also, the Su family had an oxcart, so Shen Qiuhua told her daughter-in-law to use it, making it more convenient to transport things to her parent's house.
