In Chinese student culture,
卷 (juǎn, literally 'to roll') has become viral slang meaning 'to compete intensely' or 'rat race.'
内卷 (nèijuǎn, 'involution') describes the exhausting cycle of everyone working harder just to stay in the same place. A person who studies obsessively is called
卷王 (juǎnwáng, 'rolling king').
