According to the premise of normal temperature in this season:

Spring and Autumn: In these two seasons, the average room temperature is neither too high nor too low. The average indoor temperature is about 17-25 degrees Celsius, but it is still a little higher than the preservation of duck neck. These two seasons can be preserved at room temperature for about 2-3 days.

Summer: The normal temperature and average temperature in summer are very high, and the average indoor temperature is above 30 degrees Celsius, which is not conducive to the preservation of duck neck. It can be stored for about 0.5- 1 day, but it is recommended to eat duck neck in summer as much as possible.

Winter: Winter is the lowest temperature in the four seasons, and the average indoor temperature in the south is about 10 degrees Celsius, which is also very beneficial to the preservation of duck neck, which can be preserved for about 4-5 days.
