Xinhua reports on the matter

The report says that the National People's Congress (NPC) standing committee are holding a meeting next Monday to review a delay of the annual session, slated to begin in March.

This isn't the first we're hearing of this, as there was also a report here last week.

With the coronavirus outbreak situation still gripping the country and its economy, it makes sense to push the session back a little to get a better overview of what is happening.
