Chinese sleeper trains traditionally have
硬座 (yìngzuò, hard seat),
软座 (ruǎnzuò, soft seat),
硬卧 (yìngwò, hard sleeper, open 6-bunk compartment), and
软卧 (ruǎnwò, soft sleeper, lockable 4-bunk compartment). On newer high-speed lines these have largely been replaced by
一等卧 (yīděng wò) and
商务座 (shāngwùzuò).
