Compared to Tong Liang, Xinghe's speech style was slow but steady; it fitted her personality much more. The speeches that she gave amplified that quality of hers; people could see that she was trustworthy.
In contrast, Tong Liang's speeches were kept at an all-time high. Her speeches were incendiary and spirited. Initially the crowd was excited, but several speeches later, they also started to get tired. This was because there was a limit to people's excitement levels. If the hype kept on going endlessly, the achieved effect would often be the opposite.
Tong Liang's team quickly found this weakness and they tried instantly to fix it and had Tong Liang use more slow and steady speech as well. However, that was Xinghe's signature.
The crowd had seen it from Xinghe, so when Tong Liang tried to make use of the same tactic, they felt she was copying Xinghe. After three speeches, Tong Liang's mood was low!
