TikTok's global reach makes Zhang's life "much more interesting."

Zhang wants the app to continue to grow abroad, saying that he hopes his ByteDance will be "as borderless as Google," according to the South China Morning Post.

"We must work harder, we must also be more perfectionist," Zhang said, according to the Post. "Just like there was an international division of labour in the industrial age, in today's information age there's also an international division of labour. Chinese entrepreneurs must also improve their own capabilities as they go global," he said.
