中国的30％的增幅4月份汽车行业利润一次性的？

The combined gross profit of enterprises in China’s auto industry surged 29.5% on year during April, according to the latest release by China’s National Bureau of Statistics (NBS) on May 27. The sector received a moderate boost from the rise in sales last month – reflecting the lift in demand that had been delayed by the battle against COVID-19 – but market sources warn that the handsome profits would be difficult to repeat.
