To show Filial Piety

Sheng Li was leaving for the court when Xing-Fu informed him about General Xiao. "Your Highness, General Xiao is waiting for you in the chamber." 

"Is it an urgent matter?" Sheng Li asked him. Xing-Fu looked around before going closer to the Crown Prince. He whispered in Sheng Li's ear and stepped back. 

Sheng Li knitted his brows and hastened towards his chamber. Xiao Zhan heard the footsteps of the Crown Prince and stood up from the floor mattress. "Greetings to Your Highness," he gave a fist and palm to the Crown Prince, who took his seat. Xiao Zhan then sat down. 

"What happened? Where are Brother Nianzu and his wife?" Sheng Li asked Xiao Zhan. 

"Your highness, they are living in Village Xiandong. Prince Nianzu left the town as he thought he might get caught. However, something happened in the village," Xiao Zhan paused, and lines of frowns formed on his forehead.
