What chess platform does Ding Liren use?

As Ding Liren is the World Chess Champion after competing in the FIDE World Chess Championship. He took the trophy home to China.

However, there is a question I would like to ask:
Many apps/websites are blocked in China (YouTube, Twitch, Discord). Even though, chess.com is not blocked, it’s pretty slow due to network latency which means play online has not got the best conditions as you keep disconnecting. I’m just asking what chess website Ding Liren uses in China. Chess.com is pretty good but the network latency is making my review of it decrease. I understand lichess might be a good option but it’s still slow. Does anyone know a chess website that’s fast to use in China? Thanks.

Ding Liren hasn't been in the news since he won the Championship.

However, since his pre-match prep activities were reported on during the match, It seems unlikely that Ding has told anyone if he is playing somewhere online.

Well. You can’t really block everyone. Many Chinese people especially those who have overseas life experience have some kind of VPN to circumvent the block. I believe Ding must have one, like I do.
