Thạch Xương Bồ - name of that humble prcious herb

Facebook, 2 Apr 2020, Paris, France

What time is this? Is it day or night, dark or bright? Is that Sun or Moon? ○•°●

There's a kind of herb growing both on mountain and in water, but the former is thousands times better! It is used for curing the heart (~^.^") but they are so rare now T___T so all I got [from my 父亲] is the later :")

Would you show me your true form? I won't hurt that!

Again, still those eyes... why those eyes, whose are they?
