Every morning I wake up at 6. After a quick breakfast, I catch a train to North Sydney, where I start my work for the day-house cleaning.Some of you may wonder why a college graduate like me would do such heavy physical labor(劳动). But in Australia people don't think like this. As long as you work hard, you get the respect you deserve.I usually clean houses until 4 p.m. Most of the customers are nice people who greet me, smile at me and thank me for my work.For every hour I earn 17 Australian dollars which is just over the minimur wage(最低工)line. But I'm quite happy with that. It covers my living costs, and I can even save some money for my parents and my future education.A working holiday is a good choice for young people. You get the amazing experience of living in a different country while also earning money.Once a week after a hard day, I'd go to a nearby bar to have some drinks with my friends andenjoy the beautiful night view of the Sydney harbor. It's a great way to relaxBeing in a foreign country alone, I sometirmes feel homesick. I miss the delicious minced pork rice(卤肉饭)from my hometown in Tainan. I miss my family too. But mostof the time, I enjoy my stay here in Sydney.
