What is the relationship between Chang Fei and Yu-Ching Fei?

Chang Fei is Yu-Ching Fei's own brother. As for why the two brothers have different surnames, it is because Yu-Ching Fei's real name is Zhang Yanting. Yu-Ching Fei looks like his brother Chang Fei. They also have a sister, Master Heng Shu. When the three brothers and sisters were young, their parents divorced, but this did not affect their feelings. As I grew older, my mother lived with Yu-Ching Fei, while my father lived in a house in Chang Fei.

Chang Fei, whose real name is Zhang Yanming, is four years older than Yu-Ching Fei, and is a host and singer. He once hosted a variety mobile phone, and everyone called him "Fei Ge", which is very famous in Taiwan's TV variety industry. Chang Fei usually wears sunglasses with a beard, but if he takes off his glasses, he looks like Yu-Ching Fei. They are brothers.
