No, requiring Mandarin classes in schools so they have some economic opportunities in life is not an act of genocide kiddo.

and other minorities

Unlike what happened with your grandfather, China isn't getting rid of local languages. They are requiring both in schools, the local regional language (down to microregions, so not everyone in Xinjiang has to learn Uyghur for example which would destroy more than a dozen cultures). This change simply requires mandarin to be taught alongside the local culture and language, so that Uyghurs aren't trapped in Xinjiang and can actually find work in Beijing without having to take years of Mandarin lessons.

Here's the wiki article on the law: https://en.wikipedia.org/wiki/Law_on_Promoting_Ethnic_Unity_and_Progress.

Some stuff makes sense - like economic modernization of regions with many minorities (especially poor regions), teaching Mandarin in schools so that everyone can speak the majority language, and preserving cultural works and texts of minority groups.

Other stuff seems repressive, like the broad enforcement section, the extremely broad reach of the law into all public and private institutions, legislating what various actors can/can't teach the youth if it might "harm Chinese ethnic unity" which is left pretty vague. Very ethnostate-coded stuff on the whole, not great.

Some sections I thought were noteworthy, taken from wikipedia, shortened with DeepSeek. There is lots more stuff in there.

"Chapter I.... tasks the whole of government and society to achieve these goals, mandating general obligations on a wide range of public and private actors such as ... " [basically all imaginable institutions]

"Chapter II, titled Building a Shared Spiritual Home, lays out the ideological characteristics ... requiring fostering identification with 'the great motherland, the Chinese nation, Chinese culture, the Communist Party of China, and socialism with Chinese characteristics' through patriotic education ... and promotion of 'Chinese cultural symbols and image of the Chinese nation'. It also codifies the predominance of Standard Chinese (Putonghua) in public life ... and requires that Chinese characters be displayed more prominently than minority scripts if both must be used in public."

"It tasks the Ministry of Education and the National Ethnic Affairs Commission in developing textbooks regarding 'the community of the Chinese nation' ... It vows to support the standardization, digitization, and preservation of minority texts. It broadly requires media, internet service providers, families, among others, to promote the CCP's ethnic policy ... while prohibiting them from 'instilling in minors ideas detrimental to ethnic unity and progress'."

"Chapter V and VI concern the enforcement mechanisms ... permits citizens to report conduct that 'undermines ethnic unity and progress' ... Procuratorates may initiate public interest litigation when any such conduct also 'undermines national interests or the public interest'. It generally leaves penalties to be imposed under other applicable laws. It also asserts jurisdiction over foreign organizations and individuals that 'commit acts targeting the PRC that undermine ethnic unity and progress or create ethnic division'.[7] The law empowers the state to pursue those outside of China perceived as undermining notions of ethnic unity."

Well don’t move to China!

Same here (I'm on my 3rd migration) and after 5 years I still don't even speak the language, which is embarrysing but also just fact.

If you have to ask you are not doing it right

Winnie the Pooh, probably

I think you misread the statement you're quoting. Can you elaborate on what your take on it was?

My take was "China is banning acts that undermine a general Chinese Ethnic unity or create Ethnic Division (saying one group is different than another, you know, like a cultural pride or language teaching services in their native dialect would be examples)"
