The reason Granny Yao still calls Liu Yumei "Miss Liu" and Li Zhiyuan "Young Master" is because in her heart, she still recognizes that past connection.
However, technically speaking, she is not a subordinate of the Liu family, and Liu Yumei did not previously assign her to help the young Zou Jiang. In this place Luoyang is initiated by Jiang Shui itself, and this hotel alleyway was coincidentally encountered by Li Zhiyuan.
Therefore, asking Granny Yao for help does not violate any taboo.
Even if you take it a step further, claiming causal responsibility doesn't fall on the Liu family.
Driven by Jiang Shui, Panzi, Leizi, and Liang Jun are residing in the hospital across the alley.
Li Zhiyuan suspects that among the group poisoned in the hospital ward, there may be a wave that belongs to Chen Xiyuan.
In the early morning restaurant, and the alleyway where Granny Yao's family resides, these were all prepared by Jiang Shui for Chen Xiyuan.
