Why does the ntext field in SQL show lt; long textgt;

I used access to convert it to a SQL database. One of the columns containing text content has a data type of ntext with a length of 16 and is locked. It cannot be modified and can be left blank.
When the character length is too long (thousands of Chinese characters), the corresponding fields in the database are displayed <long text>.

If the text length in ntext exceeds the limit, <long text> is displayed, because the database stores the text in hexadecimal format too long. It cannot be viewed directly, so it is displayed as <long text>. You can directly modify the SQL statement.
