I often encounter the same situation as you. Sometimes after a meeting, it's not delicious as long as you go to hot meals. Later, I bought a Dongling electric lunch box and found it really convenient after using it. You can directly heat the rice on the table without adding water. It has a built-in heating wire. Just plug in the power on the desk half an hour before going to work, and you can have a hot lunch after work. Moreover, the whole heating process is silent, and the lunch box is well sealed, so there is no need to worry about the embarrassing smell of the food disturbing others. Very suitable for office workers.
