The Sound of Happiness / 幸福的呼喚 talks aboutreminiscing the childhood days of innocence, the simplicity of life. Childhoodis undoubtedly the most wonderful period of a person’s life. Sadly once gone by, it doesn’t come back again. Sometimes people reminisce, and fondly lookback upon their youth, and say ‘I wish nothing more but to be a child again,and to go back to my childhood’. And it seems that such a sentiment is not so much for the purpose of wanting to be a child again, but rather to feeleverything to the degree of purity that we were able to feel in childhood, in which, there were fewer circumstances to taint our perceptions. The term ‘childhood’ in my point of view, enters a metaphorical territory, it means more than just an age; in the context of ‘freedom’, the term ‘childhood’ becomes an allegory which reflects any period in which it is entirely possible for an individual to revel in the simple pleasures of life without the anxiety of wanting more or filtering in antagonistic influences, and being free because of it.
