There are definitely a number of issues with Nini's current situation / education / training / upbringing - and I'll note that most Chinese skating fans agree. If we are to take the article at face value, these are a list of red flags (that remain red flags even if we compare them to training methods elsewhere):
1) Nini's mother seem to be extremely obsessed with skating and have projected her dreams onto her daughter. One should note that figure skating is an extremely niche sport in China - even more niche than it already is in the West. According to the article, Nini's mother self-studied skating for a year, spending entire days at the rink until she got all her singles. She even had an abortion due to skating. She only quit due to a nasty fall that nearly left her disfigured, and after that, tried to make Nini a champion skater from birth. She claims to have wanted a boy due to the infamous puberty/consistency problem with ladies singles skaters. She wanted to name her daughter "Yibing," with "bing" meaning "ice," hoping she'd love skating. She only changed it to "xiangyi" because people told her naming her daughter after "ice" is unlucky - but she substituted "xiang" instead which is a character used in the translated names of famous Japanese skaters Yuka Sato and Shizuka Arakawa. She started editing Nini's competition music while still being pregnant with her and started conditioning Nini for spinning when Nini was only two months old. Like come on...
2) Tiger mom training - Nini's mother says "I can at any moment yell, then smile, then become violent, then kick her, then beat her, everything is under my control, it's extreme / limit-pushing personality training." She compares herself to tiger moms and says it's her "social responsibility" to beat Nini. Nini's father has noted that "[Nini's mom] thinks Nini should rest if she's injured, if she's not injured then she should keep training. If her ankle doesn't have any issues then [her mom] gets unhappy, thinking she didn't train enough."
3) Nini's mother seems to take criticism and anything less than perfection extremely poorly and take it out on her daughter. Apparently, in 2014, Nini's mother read an internet comment that Nini is only good at spins and has nothing outside of them. Even if this is harsh, I think we can agree that plenty of fans make these types of comments even about the most talented and successful skaters (fans saying Nathan is nothing without his quads, etc). Nini's mother became extremely upset and thought, "how can I accept this? [Nini's] landed a single axel by 5 1/2 years of age, and only won every competition she's entered, what grounds does the [critic] have to say that?" She then proceeded to make Nini train extra hard, causing Nini to train 12 hours on one day. Nini's mom said "[Nini] trained until she had a fever," "I was pretty crazy then, the more they [criticized her] the more I trained her to death, because that's who I am, I don't accept losses, I can't handle them." This is an extremely dangerous and toxic mentality to have as an adult, much less to project onto a child!!
4) Nini's mom is isolating her from her peers and family, not just homeschooling her. Nini's mom describes her husband (and all men) as "giant babies" and thinks an efficient marriage is built on distance (to the extent that they text each other instead of talking in person). She thinks true elites are always "lonely" and Nini's friends should be at least 20 years older than her since she should only hang out with people who are "older and more experienced." She considers Nini's similar-aged peers as "garbage" who will only waste Nini's time and won't bring her happiness. She considers Nini's mental age to be 30+. When Nini's father tries to make Nini's training less extreme, Nini's mother fights back and recruits Nini to her side. One day, Nini's father heard Nini's mom yelling at Nini in the room and came in hoping to interfere. However, he found Nini's mom knocking her head against the wall and Nini doing the same. Apparently this is a common threat Nini's mom does to try to get Nini to be more even-tempered in training and less prone to bouts of impatience (?????)
I haven't even listed everything here, just a few things that really rubbed me the wrong way. Feel free to get more translations of the article if you want. I'd just like to say that when even Chinese fans (who are very used to tiger moms and tiger mom training) have reacted to the article by saying they feel chills going down their backs, there's some serious **** going on.
