Haha, I am also in Guangzhou. I don't want to eat outside at noon, so I often bring rice.

Let's just say, don't bring leafy vegetables, especially green vegetables, because it will taste bad and produce any toxic substances.

Try to drink less juice. Too much soup will be inconvenient.

I am a semi-vegetarian (only eating shrimp and seafood), so I don't bring much meat, but the landlord can go with vegetarian food. In fact, shrimp is very good, the color is very beautiful, and everything is delicious.

Then vegetarian dishes, it is best to bring some potatoes, melons, cruciferous, rhizomes. These ingredients are durable and not easy to change color and taste.

You can put some fruits and lettuce salad in a small box and put them in the refrigerator when you get to the company.

In addition, I like to bring a pack of dried radish and kelp. When I feel that there is not enough food, I can have dinner.

PS:

No matter in summer or winter, open the lid first, let the food cool naturally, then seal it and put it in the refrigerator.

If it's a long way to go, it's best to wrap it in a thermal insulation bag and keep it cool.
