Jiangnan in February is full of flowers, and cold food in other places is far from sadness.
Poor people often don't have fireworks, not only in the Ming Dynasty.
This poem was written by Meng Yunqing in Tang Dynasty.
The full text of this poem means that it is sad enough to spend the Cold Food Festival in another country in February with flowers all over the south of the Yangtze River. Poor people generally don't make a fire to cook, and it's not until tomorrow to eat this cold food.
