Leonid Sergeevich Vasiliev. Ethics and ritual in traditional China (№ 451908)

A respectful son, like his wife, should get up with cock crows, wash quickly, comb his hair, get dressed and immediately go to his parents. With bated breath, they should respectfully ask how they slept, if they were cold, if the bed and clothing were comfortable, if they were still experiencing any inconvenience, if they were sick. Then you need to help your parents get up, wash, take care of breakfast for them, and only after that you can leave for a while for other things.
