4 Anchal offices with the name 'Piravaka' attached to the town name.
1) Quilon. 2) Alleppey..3) Kottayam. 4) Changnacherry.
Varieties in cancellations seen in each Town Piravaka's..(not shown here), which also is an interesting study.
About Piravaka (പ്രവ്ക/ പിറവക), debate is still going on, whether Piravaka is located near a market place (Peedika.. Angadi-- പീടിക സ്ഥല൦ -- അങ്ങാടി)
or is it in the vicinity of Judicial/Government offices?
Maybe Piravaka is a Suburb/Rural or Mofussil Anchal office?
