He Yinhai is an entrepreneur from Zhejiang province who has been doing global business on portable electric hammers since the 1990s. In the past three years, his company has been severely affected by the Russia-Ukraine conflict and COVID-19. But now, under China's policy of work resumption, his company's sales volume has revived, reaching 70 percent of what it was in 2019. He said he believes all his difficulties are temporary and hopes that he can carve out a place for portable electric hammers in the future.
