Child labour is common in some parts of the world, and can be factory work, mining
[1], prostitution, quarrying, agriculture, helping in the parents' business, having one's own
small business (for example selling food), or doing odd jobs. Some children work as guides for tourists, sometimes combined with bringing in business for shops and restaurants (where they may also work as waiters). Other children are forced to do tedious and repetitive jobs such as: assembling boxes, polishing shoes, stocking a store's products, or cleaning.
