The all IIS students&staffs held the campus environmental improvement today.

The area that we should clean had many Houttuynia cordata.
We could pull out all of them.

Junming-san and Len-san said “Houttuynia cordata is eatable”.
In Japan, some tea contain the Houttuynia cordata, but many people don’t eat…I think.
But we wanna try some time.
