When will you be discharged from the hospital on the thirteenth day of the lunar calendar this month?

1, thirteen is an auspicious and noble number, which is the number of emperors.

2. Fourteen is not an auspicious number in China, which is probably related to the Chinese homonym 14. The homonym of 1 is to want, the homonym of "4" is to die, and the homonym of 14 is to die, so it is considered unlucky.
