千年洞窟的回响 Voices of the Ancient Caves

Every year, thousands of visitors are drawn to the Mogao Caves in Dunhuang. The caves were carved into the cliff over a period of a thousand years, and their walls are covered with colourful murals. Last month, the school organized a study trip, and Li Lei's group was chosen to learn about the protection of this treasure. 'The murals are protected by a special team of experts,' the guide explained at the entrance.

Inside the caves, the air was cool and dark. 'These paintings were made with natural minerals more than a thousand years ago,' the guide continued. 'They were painted by nameless artists who worked by the light of oil lamps. Because the colours are so precious, the number of visitors is limited, and photography is forbidden in some caves. A new digital project was launched last year: every mural is being scanned, so that the images will be kept forever.'

Li Lei was deeply moved. 'I have seen pictures of Dunhuang in books,' he said, 'but standing here, I can feel the hands of those ancient artists.' Han Mei nodded. 'My grandmother told me that when she was young, some murals were damaged by careless visitors. Now the caves are watched over day and night, and damaged parts are repaired by skilled restorers. It makes me proud that our generation will pass this treasure on.'

On the third day, the students joined a workshop where they tried to copy a mural with traditional methods. 'Every colour comes from nature,' the teacher showed them. 'Blue is ground from a rare stone, and gold powder is mixed into the paint.' Lily, who loves art, was amazed. 'I have never realized that so much labour and skill are hidden behind a single brushstroke. These works will be remembered by the whole world,' she said softly.

Before leaving, the students wrote their wishes on paper lanterns. 'May our cultural treasures be protected forever,' Li Lei wrote. Jack added, 'And may they be seen by more and more young people.' As the lanterns floated into the night sky, Cozy said, 'Heritage is not only about the past. It is a bridge that will be carried into the future, as long as every generation chooses to treasure it.' The students clapped, their eyes shining in the lantern light.
