When Jiang Li went to Mingyi Hall, she only brought along Bai Xue, a maid.
Although Mingyi Hall was a place where daughters of Government's Houses received their education, the discipline was strict. If it weren't for her interactions with the teachers of Mingyi Hall when she was formerly married to Shen Yurong, she would likely be entirely ignorant about it and might have become the laughingstock of many.
Jiang Youyao and Jiang Yue definitely wanted to see Jiang Li make a fool of herself, which is why they didn't bother to explain even a word to her. When Jiang Li and Bai Xue were getting on the carriage, Tonger couldn't help but show her reluctance by saying, "Miss, please come back early."
Tonger had been inseparable from Jiang Li during those eight years on Green City Mountain, when the latter had only Tonger as a maid. Now that Jiang Li had more servants around her, Tonger felt somewhat left out, and Jiang Li had to comfort her quite a bit.
