Nio was listed on the New York Stock Exchange in 2018 and William Li, founder, chairman, and CEO of Nio felt that the IPO was not a success.

He revealed in "Meet The Big Names" that Nio planned to raise $2 billion, but only ended up with $1.1 billion. The planned fundraising should be enough for Nio to "burn" for two years, but in reality, it was only enough for one year.

What made Li feel even worse was that on a public occasion, an American hedge fund investor openly said, "You are all liars.

Nio delivered 7,225 vehicles in January, up 352.1% year-on-year and setting a new monthly record. This number is 3 percent higher than in December.
