So the white triangle represents WS-21 and the yellow one WS-19?
Basically, his response is broadly similar to those exhibited by PLA fans and watchers inside and outside China towards the launching of the 003 Fujian in June last year. (doge)
That is, in 2002, we just wanted China to have a carrier of her own.
Then, in 2012, we just wanted China to have an indigenously-built carrier.
Yet, in 2022, we want China to have indigenously-built nuclear-powered supercarriers.
Hence, in 2032, we would want China to have multiple indigenously-built nuclear-powered supercarriers instead.
To put it simply - We are always aiming for the stars further ahead for every step we take forward.

Hmmm... the figures don't really correspond with open source figures.
M88-2 has a TWR of less than 8? And F414 provides less thrust than the EJ200? And the EJ200 has a TWR of closer to 10 than 9?
The XG-40 which the EJ200 is based on did have a TWR of 10 IIRC.
The white triangle are marked as the third generation engine independently developed.
The yellow one is marked as the 4th generation engine
So the WS-15 and WS-19 are China's 4th-generation low-bypass turbofan engines.

In that case, white triangle has ~9200kgf of thrust with a TWR of ~8,5 while yellow triangle has ~9700 kfg of thrust with a TWR of ~9,5-9,6.

General
Here's the full presentation for those who are interested in the long format. The talk is mainly about the basic trends of aero engine research and development, notably the use of digital design and simulation technologies and how they can increase productivity and shorten development time. Using the development of WS-19 demonstrator as an example, the testing cycles have been shortened by 25%.
