I removed your link as it is to a known malicious page.
It looks from the screen shot as though you probably have a long string of glyphs separated by non-breaking spaces, but it's hard to know without seeing non-printing characters.
but,where is my filedown's link?
I removed your link because it pointed to a known malicious page. Find someplace else to put the file.
Filedown has a nasty reputation in English-speaking countries - plenty of antivirus/antimalware apps block everything there by default, which is what Peter has done. It doesn't mean that your link is malicious, only that it's hosted somewhere that has been used to host malware in the past.
I'm pretty sure, Peter, that there aren't any nonbreaking spaces there, because I'd wager that there aren't any spaces there at all. It's justified text, and the reasons why it will or will not break are sometimes obscure when using composers that aren't the J composer. Chinese text is usually entirely free of spaces, except in certain circumstances, usually involving European language inserted into Chinese text. Sometimes, for reasons I don't understand, InDesign will simply treat Chinese as if it were English, and only break at spots permissible in Euro languages. That's not the case here - it obviously breaks between two Chinese glyphs, so something else is up here.
Which version of InDesign are you using? Are you keying the text directly into InDesign, or are you placing, or copying/pasting?
If you're using an English version of InDesign, I would suggest trying to save your Chinese text as raw text or RTF and File -> Place that. If you choose RTF, try to mark it with Chinese language in your RTF editor (Word?) if possible.
Is No Break applied anywhere in your text? You can check in the Story editor (Control/Command Y) to see what styles and formatting are applied.
And Peter, if you look at the end of the paragraph, there's an end-of-story marker - hidden characters are on in the screenshot.
Why would there be what appear to be spaces in the second line if there are no spaces? And clearly there is something in that lie that is preventing it from breaking anywhere.
@Peter – do you mean the white space after the dot at the end of the second line? Or after the commas? That is no extra space made by a blank or a separate character.
In a lot of cases the glyphs for the Chinese comma or full stop has a white area right to the drawing glyph. It's just the width of the glyph making the white space. That does make sense aesthetically, if you are not working with space characters at all.
@喜狼_edny – I suggest you are showing a bigger screenshot of the Text Editor View Window as well…
