Is it normal for residential property to give gifts to owners on holidays?

It is normal. China has been a country of etiquette since ancient times, paying attention to reciprocity, and the owners' support for the property work can also be regarded as a "gift". Therefore, in festivals, the property can prepare some small gifts for the owners as a way to close the relationship with the owners, hoping to continue to get the support of the owners in future work. But then again, judging the quality of a property company depends on the quality of the service it provides and whether the charges are reasonable.
