Today's Chinese word of the day is 死亡 which means death.
In Mandarin 死亡 is pronounced Sǐwáng.
Because 死 Sǐ and 四 Sì sound the same (but have a different tone) The number four is unlucky in Chinese culture. Even to the point that many buildings don't have a fourth floor but skip from 3rd to 5th.
我不怕死亡 Wǒ bùpà sǐwáng means I don't fear death.
