The remains of many of our ancestors had been moved in the form of ashes to a well organized mausoleum that was built in 1993.The government probably took over the original grave sites for various development and help built the mausoleum to replace the grave yard. There were people making donation for the building and maintenance of the Mausoleum as well.
It would be interesting to find out how many of our ancestors had been moved to the Mausoleum. It will take some efforts to match names on the urns to the names in the Book.
