The Mandarin Chinese phrase '就此 (jiùcǐ)' is used to indicate the meaning 'as a result' or 'thereupon'. It is usually used in conjunction with a preceding event or situation to express that something is a direct effect or response to this action or situation. It can thus be compared to English expressions like 'then', 'therefore', or 'as a result'. A significant property of '就此 (jiùcǐ)' is that it often implies an immediate or abrupt action or change.
