397, Doubt, but afraid to ask

What exactly did Shi Yuhuan mean by what he said? Why did she vaguely feel that Shi Yuhuan was telling her that her brother was indeed not dead and she hoped that for her brother's sake, she would stop doing meaningless things?

So, did Shi Yuhuan know that her brother was still alive, and were they still up to something?

Of course, all of this was just her speculation.

But, her insistence that the corpse was not her brother was not unfounded. It was because she noticed a very tiny detail.

Her brother always had a parted hairstyle, complete with bangs.

What everyone probably didn't notice was that her brother had a widow's peak. The hair in the middle of his forehead grew a slight bit further, forming a tiny bit of sharpness. Seen from the front, the entire hair resembles an "M," symmetrical on both sides of his temples.
