I apologize for bringing it up, and I did read the thing on the top of every page.
My problem is: I'm a player of Minecraft China. Minecraft China is an official, modified-for-China version operated by a Chinese company, Netease. The modifications require Forge to work, for some reason. Then you can guess it: we Minecraft China players cannot play 1.13 on Minecraft China.
I understand that 1.13 is very different from previous versions, and development can take a lot more time. I hope development of Forge for 1.13 can go smoothly so that Chinese players can play 1.13 earlier.
