Ebo Tai, the first star observatory of China is 1.5 kilometers from Shangqiu Ancient Town. According to records in historical books and folktales, in remote antiquity, Qi, the son of Emperor Ku, stayed here to operate kindling spark so that people could use fire at any time (That is why people called him God of Fire).Also, he observed the orbit of Mars in order to inform people to prevent disasters and plant seeds and gather in corn on time. When the Taisui Star appeared during Maoshi, it was called Danyu. When it appeared during Jiawu, it was called Yufeng. Maoshi referred to morning, and Jiawu is the first in the Heavenly Stems. Thus Danyu and Yufeng attracted much of people’s attention. As time passes, Qi, who observed the relation between Mars and Taisui star and their locations, was called “Ebo” by people at that time. After his death, people buried him in the high place where he observed Mars. Later, people call his tome as Ebo Tai or Mars Tai or Huosheng Tai.
The Ebo Tai preserved today is of tomb shape, 35 meters high, with a 270-meter-circumference. It was built of ramming clay. Tiles and pottery were among tier upon tier of ramming clay, which might come from Han Dynasty. Because of the sand and mud sludge of the Yellow River, the original Ebo Tai is dimly visible under the present one.
The dune under Ebo Tai is the place which Ebo conferred as Shangqiu. This is the way Shangqiu gaining its name. Erected on the plain which stretches to the horizon, it looks much taller and loftier. It is the highest point in the ancient Shangqiu towns, along with the thought of ancient people that Ebo Tai complied with Shang Star; it has been regarded as the symbol of Shangqiu since ancient times.
On it stands the Ebo Temple, which is architecture of Yuan Dynasty. The temple consists of audience hall, worshiping hall, the eastern and western Buddhist gates, wing-suites, and bell tower. The hall is resplendent , magnificent, and it is a typical national architecture style. It has been renovated for several times since Ming and Qing Dynasty. And in 1981, it was repaired again. Every year, on the 7th day of the 5th lunar month, people in this area will come here and worship. People called it “Chao Tai”, and it lasts until the 2nd day of the2nd lunar month. People who come here for worshipping in this period come up to tens of thousands of people.
