Standard Linux mint is is Ubuntu based, LMDE is debian based. Completely different depending on the issues they had.
Edit: but also plenty of other Debian based distros, including Debian itself would avoid direct Ubuntu (Canonical) and Fedora (RedHat) influence.
By what metric?
China has the world's largest HSR network at 45,000KM, 15x that of Japan's 3,000KM network.
Chinas fastest regular use line is 350KM/h. Japan's is 320KM/h.
(AFAIK) China is the only country with an operational maglev line (in Shanghai). A 30KM line at 430KM/h. While Japan's Maglev is still under construction.
So what are the metrics that Japan's rail system cooks China?
