Chinese Sentence does not wrap correctly within a Paragraph

I tried to display the following sentence within a Paragraph but it does not wrap the Chinese sentence correctly. I tried DiscretionaryHyphenation, No Wrap as well as By Words, they all look weird.
The DiscretionaryHyphenation puts a dash in almost every sentence, no wrap cut off the sentence and By Words put extra space in between characters.

Can you please help and let me know what I missed?

Aspose.Pdf.Page pdfPageBios = (Aspose.Pdf.Page)pdfDocument.Pages[pageNumber];
TextBuilder textBuilderBios = new TextBuilder(pdfPageBios);

string sampleString = “William先生現任董事總經理兼投資組合經理,亦是ABC 按揭及房地產相關機會策略的首席投資組合經理之一,掌管ABC於歐洲公共及私人按揭、房地產及專門金融市場的機會投資”;

TextFragment biosFragment = new TextFragment(sampleString);

biosParagraph.FormattingOptions.WrapMode = Aspose.Pdf.Text.TextOptions.TextFormattingOptions.WordWrapMode.DiscretionaryHyphenation;

biosFragment.TextState.Font = FontRepository.FindFont(“PMingLiU”);
biosFragment.TextState.FontStyle = FontStyles.Regular;
biosFragment.TextState.FontSize = 10;
biosFragment.TextState.LineSpacing = 6;
biosFragment.TextState.ForegroundColor = Color.Black;

// add fragment to paragraph
biosParagraph.AppendLine(biosFragment);
textBuilderBios.AppendParagraph(biosParagraph);

pdfDocument.Save(outputFilePath);
