According to the Youtube community post of the famous Chinese warship and warplane 3D modeler 西葛西造舰:
对于这个模型,目前发文者称,是中船集团下属的大连造船厂某重要庆典仪式活动中专门订购的一个模型。实际情况还待考证!
Rough translation:
For this model, the posted claimed that it is a (ship) model specially ordered by Dalian Shipyard, a subsidiary of China Shipbuilding Group, during an important celebration ceremony. The actual situation still needs to be verified!

There was a model of 003 Fujian 10 years before the visible start of construction, which showed the Dalian Shipyard with aircraft carrier. So why not have a model now, which at least in its external dimensions corresponds to the next draft but one.

Edit: Penant number #20 is exemplary only.

Why straight from CV-18 to CV-20? Will there not be a CV-19??
If Dalian Shipyard really does mean their intentions with the CV-20 model , my guess is that CV-19 could be a modified and improved version of CV-18 Fujian. Perhaps the ship class for CV-19 could either be 003 (as a sister ship to Fujian) or 003A/B, instead of 004.

If the CV-19 is a 003A/B instead of just 2nd 003, IMO, the modifications and improvements on CV-19 over Fujian could include:
1. Longer flight deck towards the fore to avoid the jet blast deflector on the forward port side catapult launch position from interfering with the landing deck;
2. A portside deck elevator; and
3. More optimized (perhaps smaller) island superstructure than the Fujian
But still using similar conventional propulsion systems as the Fujian.

Before we continue on the following, one important thing to note: While Dalian has experience of building a STOBAR carrier (Shandong), Jiangan has experience of building a CATOBAR supercarrier (Fujian).

However, when talking about CV-19 and CV-20 - Recall that the Jiangnan Shipyard leadership team visited Bohai Shipyard in mid-2020:
The top leadership of Jiangnan ship yard recently paid a visit to Bohai shipyard to conduct detailed exchanges on product development and personnel training, etc. This visit follows up on earlier exchanges between the two shipyards.

Of course, Bohai has a lot of experience building nuclear-powered submarines. Jiangnan has no experience with nuclear power plants. I wonder if this exchange has to do with the future nuclear icebreaker, which is likely to be built at Jiangnan.

As @by78 has noted, Bohai has a lot of experience of building nuclear-powered ships and submarines, while both Jiangnan and Dalian do not.

Another relevant piece of information is the news of the construction of a dedicated onshore boiler testing facility in Jiangnan, dating back as early as 2020 or even 2019:
For what is worth, Jiangnan is building a dedicated onshore boiler testing facility. This facility will allegedly be used to verify the steam supply system of China's carrier nuclear reactors. The test boilers will be able to generate enough steam and steam pressure to test the bearing capacity of various pipes and valves as well as the steam turbines destined for the nuclear carrier.

The boiler testing facility at Jiangnan could very well be a direct result of collaboration and cooperation between Jiangnan and Bohai on the subject of marine nuclear propulsion.

In retrospect, while there are such news between Jiangnan and Bohai, there have been no such news (or at least that we are aware of) coming out between Bohai and Dalian. So it does come as a genuine surprise to me that Dalian would have the nuclear-powered CV-20 model in a celebration ceremony.

In fact, it would be a much bigger surprise if Dalian is the one to build China's first ever nuclear-powered supercarrier instead of Jiangnan, considering that Jiangnan is already well in-progress of developing boiler technology for use on marine nuclear reactors.

Therefore, it does beg two huge question marks:
1. Would CV-19 be conventionally-powered (003 or 003A/B) or nuclear powered (004)?
2. Would CV-19 be built in Jiangnan or Dalian?

Can someone tell me what these two lines are? They don't seem to be painted by people with military common sense.

Foul Line: A line painted on both sides of a landing or take-off area to define the minimum area that must be free of obstructions in order to consider the deck clear. The top line defines the obstacle free area of the port catapult, the bottom line the area of the starboard catapult. Should be parallel to the catapult track, that is the mistake, the painting people did.
