Three Possibilities

Zhan Wuya told Sheng Xiao, "My mentor is already quite old, so he has as many as a hundred disciples under his name. Senior Brother Sheng Pinghui was one of them, but many of my senior brothers and sisters have died already. I joined the sect late and was my mentor's last disciple, so I have never seen many of my senior brothers and sisters. But every Sacrifice Festival, my mentor will bring me and the other senior brothers and sisters to pay respects to those who died."

"Because I have to toast my fallen senior brothers and sisters every year, I have some impression of that senior brother called Sheng Pinghui. I remember that about twenty years ago, I asked my mentor about Sheng Pinghui's deeds and he told me about it."
