Taiwan's economic growth the lowest Since 2012.
Taiwan's economic growth rate is at least three years because the export sector plummeted in the midst of his flagging global demand and increasing competition from the countries around. Gross domestic product (GDP) rose 0.64% in the three months to June compared to the previous year, according to the data released by the Statistics Department of Taiwan last Friday.

Hi William,

Thank you for prompt response but it doesn't help me as I'm not that good in coding.

Thanks for additional help.
