In English, it means Chinese New Year is here and that river of red translates into a cash flow of green for local resorts.

During the past 30-plus years, resorts have been reaching out to their Chinese customers, inviting them to celebrate the new year in Las Vegas. And they've been accepting the invitation, because Las Vegas is the perfect city to engage in that one major holiday tradition observed by the Chinese: gambling.

"The expression of luck and fortune at the beginning of the year is an ancient Asian tradition, especially among the Chinese," said Alan Feldman, senior vice president of public affairs for MGM Mirage. "It's a very important event for us in the industry and one that is recognized on Wall Street."

The Chinese New Year, a 15-day holiday, is set by a lunar calendar and usually falls in January or February. Today marks the first day of the Year of the Rat, which signifies prosperity and wealth. It's the first of the 12 animals that make up the Chinese zodiac.

The first property to reach out to Chinese guests was Caesars Palace more than 30 years ago, says resort President Gary Selesner. Management decorated and had a lion dance, a traditional Chinese dance that is thought to summon luck and good fortune while driving away bad luck and evil spirits.

"In the first few years, it was really for the high-end players, then more properties began to reach out," Feldman says of the holiday celebrations. "There's always such a focus on luck, we just sort of fit right in, and by adding these cultural attributes" such as the lion dances, special foods and entertainment, Las Vegas began to appeal to a wide audience.

Now the celebration is everywhere, in all levels of business, Feldman adds.

Asian restaurants extend their hours and offer special, holiday-related dishes. MGM Grand brought chefs in from Beijing this year to prepare a special banquet to be served throughout the holiday.

Resorts also book entertainers that are popular with Asian guests and schedule lion dances.

Children from The Meadows School have been performing a lion dance at the Forum Shops at Caesars for the past 12 years, notes teacher Linda Verbon.

In 2006, Asians accounted for 36 percent of the gaming revenue during the Chinese New Year, says David Huang, president of Chinese Hosts, a travel company that books rooms, entertainment and tours for Chinese tourists.

Caesars has experienced double-digit increases in revenue at the gaming tables during the past three years, Selesner says, mostly on baccarat, which is the game of choice for Asian players.

Chinese New Year has become an important niche event for the city, taking a part of the year when tourism often is flat and bringing in guests and revenue, says David Schwartz, director of gaming studies at the University of Nevada, Las Vegas.

"I think it's going to become a lot more competitive and casinos will try to outdo the other," Schwartz says. "It will be good for customers, they will have more to choose from."
