Yueyao sent someone to send a message to Tingzheng, that she would be going to the Summer Mountain Villa for at least two months. She wouldn't be able to see Tingzheng during these two months.
Upon hearing that Yueyao was going to be away and they wouldn't see each other for two or three months, Tingzheng, holding Yueyao's hand, said, "Sister, I'll go too." When he had vacation time, he could still visit his sister at their uncle's house, but now that she was going to the Summer Mountain Villa, he wouldn't be able to see her for two or three months, which filled his heart with unhappiness.
Yueyao, stroking Tingzheng's head, thought that Tingzheng had also grown up and should learn to be independent; he couldn't always rely on her. In a gentle voice, Yueyao said, "Sister has business to attend to at the villa this time, and besides, you need to attend your lessons. You mustn't neglect your studies."
