Yes, Xiaomei said in the TV series that she was able to cut the eggplant into that shape because she used a special knife method: the coir raincoat knife method

Coir raincoat-shaped flower The knife is used to cut one side of the raw material like a wheat ear-shaped flower knife, then turn the raw material over and cut it again with the push knife method. The knife pattern is cross-cut with the oblique cross knife pattern on the front. The depth of the knife pattern on both sides is about the thickness of the raw material. Four-fifths of the way, the raw material processed in this way is lifted up and has holes on both sides to form a coir raincoat shape.

The specific method is as follows: wash the long eggplant, remove the stem, tilt the knife 45 degrees to the left, about 5 mm apart, cut it into two-thirds, do not cut off the bottom. Turn the eggplant over, tilt the knife 45 degrees to the left again, and cut into two thirds without cutting off the bottom. This kind of knife method is called the coir raincoat cutting method. The inclination of both sides is exactly opposite, so the eggplant will not be cut off. When cutting the coir raincoat cucumber, put a chopstick at the bottom, but the eggplant is thick enough, so just take your time, and you don't need to cut it so thin, only about 5 mm. After cutting everything, just pull it apart.
