Zhou Shaoliang, editor-in-chief of Epitaph Collection of Tang Dynasty (Shanghai Ancient Books Publishing House, 1992 edition), published Arahan's epitaph on page116, saying that he "looked at the people of Persia (Iran). In the middle of the Xianqing Dynasty (656-660), Gao Zong was called here as a general because of his outstanding achievements. ..... and for the sake of the Great Sage Queen, I called all the fans to build Shu Tian. " The newly acquired Epitaph of Luoyang (Beijing: Cultural Relics Publishing House, version 1996) contains the epitaph of Gao Zuyou unearthed in Louzigou Village, Pingping Town, Yichuan County in 1990, calling Gao Zuyou "a native of Pyongyang, Liaodong" and worshiping him as "a general of the town army and a general of Zuo Wei" after coming to Luoyang. "Shengyuan year (that is, the first year of Tian Shu), Shu Tian, Yu Yuezi, carved it. Gan Qing soared into the sky, showing that he was proud of himself.

Arahant and Gao Zuyou belong to the "Four Qualities", and their names can be tested. It can be seen that Shu Tian is an architectural artwork designed and built by a Sino-foreign joint venture.
