When asked how he decided on the winning bid of $2,345,678, Zhu said he was inspired by the stock quote of his company, which is 002354 on the Shenzhen Composite. He added that the staggering bill for the luncheon - to be held at Manhattan's Smith & Wollensky steakhouse - would not be put on company expenses.
Zhu is not the first Chinese businessman to secure the winning bid in Buffett's annual charity lunch auction. In 2008 mainland investor Zhao Danyang paid $2.1 million for a meal with the so-called Sage of Omaha.
Last year's winner, Singapore's Andy Chua, paid almost $2.2 million for his chance to dine with Buffett. The highest bid in the auction's 16-year history was $3,456,789 - made in 2012 by a winner who chose to remain anonymous.

So, what is Dalian Zeus Entertainment Group?
Formerly named Dalian Kemian Wood Industry, the firm originally dealt with the manufacturing of flooring and wood products, but is now mainly engaged in web and mobile game development.
The Dalian-based company has seen its shares surge almost 70 percent this year, bringing its market cap to 21.62 billion yuan ($3.49 billion). But its stock has been in a trading halt since May 28 pending the release of an announcement, according to Reuters.
For the past 16 years Buffett has donated the proceeds of his annual lunch auctions - more than $17 million in total - to Glide, a San Francisco charity that aids the city's poor and homeless.
