Think of those who have made contributions from obscurity to street lamps.

Street lamps, the eyes of the city, illuminate the darkness at night and bring people safety and convenience. However, while enjoying the convenience brought by street lamps, have we ever thought about how much effort and sweat people behind us have put into making street lamps work normally?

First of all, we want to thank those hard-working electric workers. In the hot winter and summer, they fought day and night in the front line of power line maintenance and repair, regardless of hardships. They are always vigilant and ready to deal with all kinds of emergencies to ensure that street lamps can supply power normally. Their hard work makes us feel no longer afraid and uneasy when walking at night.

Secondly, we want to thank those unknown cleaners. Every morning or late at night, they shuttle through the streets of the city and clean the garbage and dirt under each street lamp with their hands. Their hard work enables us to breathe fresh air and walk on a clean road every day. Their contribution makes our city more beautiful and livable.

Third, we want to thank those unknown maintenance workers. They are always ready to stand by. Once the street lamp is broken, they will quickly rush to the scene to repair and replace it. They are skilled and can quickly find out the cause of the failure and repair it in time. Their hard work makes our city as bright at night as during the day.

Finally, we would like to thank those unknown designers and engineers. When they designed and built street lamps, they considered many factors such as illumination and energy consumption, which made the street lamps more energy-saving and environmentally friendly and met people's needs. Their wisdom and creativity make our city more modern and intelligent.

In a word, the unknown people behind street lamps may not be known, but their contribution can not be ignored. It is because of their hard work that we can feel safe and comfortable when walking at night. Let's thank these unknown people together and make our city better!
