Zhao means speed and super-teng. The Dongyi tribe in the Shaohao period used birds as their totems. In the clan emblem with the black bird and phoenix as the clan totem, the "Xiao" graphic should represent Xuan. Birds and phoenixes are enshrined on the sacred table on the right, and a speeding human figure is on the left to show the functions of the worshiping clan. Later, Zhao was also extended to the charioteer who drove for the emperor, so in ancient times, the three characters Zhao, Xiao and Yu were synonymous with each other.
That is Zhang Siyu or Zhang Sixiao
