Founder of Changu Narayan; not Mandev

Changu Narayan Temple, one of the most beautiful World Heritage Sites, stands on a hilltop at the eastern end of the valley, about 6km north of Bhaktapur and 22km from Kathmandu. It came in existence in 4th century. Whenever we ask anyone about the establishment of this traditional beauty, everyone says it’s Mandev who built Changu Narayan. But people are not aware of the fact that it was not Mandev, it was King Haridutta Burma who actually built the Changu Narayan.
King Haridutta was the ruler 9yrs before Mandev. In the inscription of Mandev, the works for making guthis and land has been mentioned but there is nothing about Mandev's contribution in building the temple. Had it be the Mandev, there would have been the name of the founder as Mandev. There are other works mentioned in the inscription but not about the establishment.
