Yicheng Luo (also known as 白水, 罗义诚 or Takuto Luo) is the owner of 91yoyo Workshop, Team Imperial and the defunct Takuto.Design, the second manufacturer to produce high-end aluminum yo-yos in China. He has become popular in the Chinese yo-yo community when he filmed trick videos, written books about yo-yoing, performed live on TV shows. He started 91yoyo.net and 91yoyo.com, two leading online yo-yo communities in China.
In early 2006, just after winning 2nd place at the AnY MiRoC Video Contest, he shot a series of instruction videos, which includes beginner and advanced level tricks hosted at yoyonation. After that, he got an invitation from a book publisher to write a book about basic yo-yo tricks.
He joined Auldey in 2008. In the same year, he entered the World Yo-Yo Contest and became the first Chinese contestant to bring the banner of China onto the international yo-yo stage, finishing in 4th place. He established 91yoyo.net that year with a few companions.
From 2010 to 2011, he competed at a few international contests, usual making it to the finals, except at the 2011 Worlds.
Yicheng Luo left 91yoyo.net in 2011, due to disputes with his co-workers. He had then established 91yoyo.com.
In June 2012, his contract with Auldey expired.
In Summer 2014, he launched his patented design, the L5 Wave, on YoYoExpert.Com, his products successfully reaching players overseas.
In April 5, 2015, Yicheng Luo started Team Imperial (中华龙之队).
