②-1: Stir with a spatula until combined, cover the bowl with a damp cloth, and let it rest for 30 minutes.
②-2: Dust the work surface with flour, turn out the dough, and knead or slap it for about 5-10 minutes, shaping it into a round.
②-3: Lightly oil the bottom of the bowl (to prevent sticking), place the dough back in the bowl, cover with a damp cloth, and let it rise for about 90-120 minutes until it doubles in size.

【Shaping】－To prevent sticking, use flour as needed
④-1: Dust the work surface with flour, turn out the dough after the first fermentation, and gently press to release air.
④-2: Divide the dough into 4 equal parts, shape into small rounds, dust with flour, and let rest for 15-20 minutes.
④-3: Take one piece of dough, roll it into a long strip, and evenly spread one portion of walnuts and chocolate chips on it.
④-4: With the dough perpendicular to you, seal the sides, and twist the top and bottom into a knot.
④-5: Shape each piece of dough in sequence, arranging them with space on the parchment paper.
