Children in Hong Kong take education for granted, but things are different in Nepal. During the summer holidays, 56 Hong Kong students went to the mountainous country to learn about the work done by the United Nations Children's Education Fund (Unicef).
They visited an area in the capital, Kathmandu, where they got a first-hand view of the way some students have to live and learn.
Unicef has joined with local institutions to help children in many different ways. Their Urban-Out-Of-School programme helps under privileged children learn to read and write, along with teaching them basic life skills, such as hygiene. The reasons for children not being able to go to school are numerous:
'I have to take care of my baby sister,' says one youngster. Many of them have to work, in restaurants or hotels, as domestic servants or rag pickers, or even helping on construction sites and in sweet factories.
Their families, if they have any, depend on them for their income in this poverty-stricken country that has been torn apart by years of war.
It is hard for the youngsters to go to regular school, so the Unicef programme offers them classes out of the normal schedule. It also gives them books and stationery - luxuries they would normally be unable to afford.
Meeting the envoys was a treat for them and an eye-opening experience for the Hongkongers. It was a glimpse into a world they would rarely see.
