1. Peel the yam and steam it in a steamer for about 7 minutes. At this time, the yam still looks completely ripe and slightly hard, but there is no mucus on the surface and it is very dry after cooling. Wipe the dried yam into filaments, and operate with a silk wiping tool.
2. Beat in 3 eggs and add chopped green onion.
3. Stir roughly first.
4. Add flour and baking soda.
