I'm confused about why this sentence from my textbook begins with 行文至此.

> 
> [CC-CEDICT](https://www.mdbg.net/chinese/dictionary?wdqb=%E8%A1%8C%E6%96%87): 行文 (xíng​wén​) writing style (formal) / to send an official written communication  
> 
> [CC-CEDICT](https://www.mdbg.net/chinese/dictionary?wdqb=%E8%87%B3%E6%AD%A4): 至此 (zhì​cǐ​) up until now / so far
> 
> 
> 

Judging from the above, 行文 seems illogical (missing definition?). And 至此 is just another way of saying 至今.

**Question**: What does 行文至此 mean in 行文至此，北京市职业介绍部门传来令人欣喜的消息……?
