The removal steps are as follows:

1. Prepare the necessary tools: scissors, sewing machine, sewing thread, needles, etc.

2. Turn the down jacket over and find where the logo is.

3. Use scissors to carefully cut off the lines around the logo, keeping the cuts neat.

4. Use a sewing machine to sew the edges of the cut. You can use the same color thread as the down jacket to maintain the overall beauty.

5. Check whether the suture is firm and re-sew if necessary.

6. Use scissors to trim off excess thread.
