Introduction to the Jiyuan Terrace: The Jiyuan Terrace is a platform for worshiping the king of the year. The totem in front of you is the totem of the Dongyi tribe, Bird Yi. When the king was old, he held sacrificial activities on this platform, offering sacrifices to heaven, earth, ancestors and the country, praying for good weather and peace of the country. At the same time, this place is also the oath platform. King Ji led his ministers and people to swear an oath on this platform: work together, practice hard in military affairs, and be determined to restore the country, expressing King Ji's determination to restore the country.
