The specific steps to gather the hair of Ruoxi and Yongzheng before consummating their marriage (it seems to be pinned with a hairpin) are as follows: 1. Comb your hair neatly and divide it into two parts. 2. Use a hairpin to insert a small portion of hair into one side of the hair and tie it up. 3. Use a hairpin to insert a small part of the hair on the other side and tie it up. 4. Tie the two strands of hair together with a hairpin to form a simple bun. Finally, you can use other hair accessories such as hair clips, hair crowns, etc. to further decorate the bun to make it more beautiful. It was necessary to pay attention to the depth and angle of the hairpin to prevent the hair from being damaged or broken. At the same time, different types of hairpins and materials would also affect the appearance of the hairstyle. It needed to be adjusted according to the specific situation.
