 Here is all the code:

using System.Drawing;
using System.Linq;
using System.Text;

namespace insert_new_paragraph_and_hide
{
    class Program
    {
        static void Main(string[] args)
        { //This part is the code to insert a new paragraph
            Document document = new Document();
            document.LoadFromFile(@"C:\Users\Administrator\Desktop\向日葵.docx", FileFormat.Docx);

            Paragraph paraInserted = document.Sections[0].AddParagraph();
            TextRange textRange1 = paraInserted.AppendText("The flower language of sunflower is - sun, brilliance, pride, loyalty, admiration, silent love. Sunflower is also called Wang Rilian, a beautiful name");
            textRange1.CharacterFormat.TextColor = Color.Blue;
            textRange1.CharacterFormat.FontSize = 15;
            textRange1.CharacterFormat.UnderlineStyle = UnderlineStyle.Dash;
            document.SaveToFile("result.docx", FileFormat.Docx);


            //This part is the code of the hidden paragraph
            Document doc = new Document();
            doc.LoadFromFile(@"C:\Users\Administrator\Desktop\雏菊.docx", FileFormat.Docx);
            Section sec = doc.Sections[0];
            Paragraph para = sec.Paragraphs[sec.Paragraphs.Count - 1];
            for (int i = 0; i < para.ChildObjects.Count;i++)
            {
                (para.ChildObjects[i] as TextRange).CharacterFormat.Hidden = true;

            }

            doc.SaveToFile("result1.docx", FileFormat.Docx);

        }
    }
