How to make beyond the 42 length of the back automatically add ... A little bit.

There is a piece of code on the home page, in fact
Add yourself ..., why do you need to add
PHP Code
{dede:arclist flag= ' h ' limit= ' 0,1 '} [field:title/]
[Field:description function= ' Cn_substr (@me, 110) '/] ... [View full text]
