Tips
history
From Han Yu's 《后十九日复上宰相书》 (Tang dynasty): '行且不息,以蹈于穷饿之水火,其既危且亟矣,大其声而疾呼矣' — the scholar described himself as shouting urgently like a man in the fires. The 疾 ('urgent, quick') here means 'with urgency', not 'illness'.
mistakes
疾 is 'urgent' here, not 'illness'. Learners often mistranslate as 'to shout in sickness' — it means 'to shout urgently'.
