Good at keeping secrets

"How can you eat so much?" Jin Fengming asked in bewilderment as he watched Yu Chen, who already had a bowl full of Baozi (Steamed buns filled with various meats or vegetables) and Dim Sum (dumplings). 

"I couldn't have breakfast and lunch since I was in a deep slumber," Yu Chen asserted and thanked the boy, who brought the second serving for him. 

"We need to help the Crown Princess," Cao Jun asserted.

"And how will we do that?" Yu Chen inquired as he stirred the chopsticks inside the bowl of Baozi. "We don't live in the palace, so helping Her Royal Highness is impossible for us," he proclaimed. 

"It is not impossible," Cao Jun affirmed. 

"I have heard the Emperor's younger brothers have called upon a secret meeting. My father mentioned it in the morning. Your fathers must be taking part in that," Yu Chen stated. 

"I haven't heard of it from my father," Cao Jun said and picked up the dumpling to eat.
