That is very cheap take. Just look at e.g. CNSAs own web page: http://www.cnsa.gov.cn/english/index.html or the main producer for space systems: http://english.spacechina.com/

Compare and contrast any content on there to what NASA is providing on e.g. Perseverances mission page: https://mars.nasa.gov/mars2020/

I can't even find homepages for Tianwen-1 / Zhurong. That is hardly because "media is cherry-picking negative stuff".

Western media cherry picks negative things about any country that isn't under the US's thumb. It's wild how much xenophobia US media causes that people aren't seeing, especially around Russia and Russians. Americans think of Russian leaders as awful people while also praising liberal US presidents that have continued death and destruction on foreign countries too.
