From the information, the children aged 5-17 years about 8,327 persons, 822 of them were child labourers. It is too much in range of age 5-17 years who must work. So, we interested to research this topic because we think child labor problem is very important in Thailand. The children should study in school and take time to do something that improve their learning such as play cross word game for improved IQ and EQ skills, play sport for improved their healthy, etc. But, we can see that children work more than we think. Thus, we should research about child labor to know that is not only negative point, but also positive point.
