This has been looming for quite a while and is now public news. She of the glorious oversplit leaps and particularly amazing beam, but also epic meltdowns such as 2011 TF floor, has retired. I'd hoped when she re-emerged last year with some very nice work that she'd make a full comeback, and we may see her yet at small competitions and maybe Asian Games if they need her, but she will not be in the running for major international competitions.
I know this would be better with a source, but Chinese news is secret and when made public as in this case, it doesn't come with official sources. Unfortunately, many girls fade away quietly, the prime example being Zeng Siqi earlier this year.
Wishing her a happy and healthy future.
