In China, the most popular and the only CTTA-approved rating is 开球网/kaiqiuwang (literally "Open Ball Net", or "Game Start Net" in proper English)/ChinaTT (official English name). The OP would be roughly in the range of ChinaTT 1800-2000.

(Meaning: ChinaTT is short for China Table Tennis Rating System, which quantifies the playing level of table tennis players in the form of ratings, in order to better create a fair and reasonable competitive environment. ChinaTT ratings were launched in 2009 [16] and are currently the only rating system recognized by the Chinese Table Tennis Association [4-5] [8]. The ratings range from 800 to 3000 and are used in 24 provinces in China and 5 countries abroad [16].)
开球网的初始积分怎么计算？ (How is the initial rating calculated at ChinaTT?)

(Generally, your initial rating is determined based on your skill level:
400 for beginners;
600 for getting the ball onto the opponent's side of the table;
800 for holding a few rallies;
1000 for receiving a spinny ball;
1200 for mastering pushing, blocking and attacking;
1400 for adding spin, placement and being capable of looping on top of the former basis;
1600 for integrating serves with attacks plus slow loops and power loops;
1800 for consecutive and consistent attacks and footwork, and the ability to trade blows with various rubbers;
2000 for being one of the top players in your local table tennis club;
2200 for having a ranked finish in provincial competitions;
2400 for having a ranked finish in national competitions;
And beyond for being a professional.
There are three ways to assign a rating before your first rating tournament:
1. Start with 0 points;
2. Have the club manager assign a rating for you (if they're familiar with you, they could assign one according to the rules above; if not, practice with them a few times to get a general idea);
3. Assign your own rating – you can assign 1400 or 1800 (generally, someone who has been playing for about two years and knows some serving set plays would be around 1500). The club manager will usually cooperate and assign you a rating.
The worst thing about rating-based tournaments isn't encountering someone with 2000 points, but rather sandbaggers with 0 points. After a match, if you lose, you lose 50 points, and if you win, you don't gain many points – keep in mind that winning against someone with a similar rating only adds about 4 points.
Don't be fooled by those short videos that boast 2000 or 2300 rating. Even less skilled comedy content creators like 嗙仓/Bangcang, 重庆冷馆长/Chongqing Upset Club Manager, and 木鱼/Wooden Fish, despite lacking professional backgrounds, spend far more time at the court than the average person. Yet, they rarely exceed 1950 rating. For those playing around three times a week (not formal training), they would typically only reach around 1600 rating after two years.)
