Sacrificial rites for delivering the ghost on lunar July 15th were performed mainly at the Main Altar situated in Chong-cheng Park. The Main Altar in early days (1851), due to "Changchow and Chuanchow Clash", was temporarily set up on Hsin-tien St or Tsou-wai-tien St. In 1929, a permanent Altar was built in Kou-sha Park. Due to traffic congestion during the rites, it was later transferred to the present location in Chong-cheng Park. The Main Altar started construction in 1970 and was finished in 1974. From the Altar situating on mountain top, a panoramic view of the harbor and the City is in sight. When all lamps are lighted, faraway view of glittering lights of the Altar can be seen from different parts of the City, bringing nostalgic atmosphere.
