Ancestor worshipping is to fulfill one's filial duties. When we respect and look after our ancestors, they remain to be our guardian angels offering us assistance, wisdom, and support. In Feng Shui studies, filial piety affects your success in life. Do take time to do tomb-sweeping for your ancestor.
