I tried this dish several times many years ago. Misgurnus anguillicaudatus is lively, tofu is tender, and heating is slow. Practice has proved that Misgurnus anguillicaudatus can't drill tofu.
I admire the imagination of gourmets, and I also admire the development of latecomers, but everyone who has done it will find that this is a misinformed story.
Haha, the loach in "The Loach Drives Tofu" probably didn't get into the tofu by himself.
