The Chinese had their own idea of zero. The Chinese had originally used a positional system called the Chinese Rod-Numeral System. Certain formations of the rods meant different numbers. Red rods meant positive numbers when black rods represented negative numbers. To represent zero, there would be a blank with no rods to indicate that there was no value there. 

Some scholars believe that zero was a Babylonian concept which found its way to India but others give India credit for developing the number. The concept of zero first began in India around 458 AD.

"Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628 AD."

Brahmagupta developed a symbol for zero: a dot underneath numbers. He turned the idea of zero into a number. By doing this, Brahmagupta broke the barrier of the unknown, as he had defined zero explicitly and gave it an identity; which had never been done before. 

"It is India that gave us the ingenious idea of an absolute value; a profound and important idea which appears so simple to us now that we ignore its true merit. We should appreciate the grandeur of the achievement the more when we remember that it escaped the genius of Archimedes and Apollonius, two of the greatest men produced by Greek antiquity."

This is a page of the Bakshali Manuscript containing the numeral zero. This is currently the oldest representation of zero as a number.

As mentioned in the video, the Babylonians had an idea of zero. This is the ancient Babylon placeholder for zero. The placeholder is believed to have come from the Sumerians.
