It's party time!

    Back-to-back holidays mean big bucks for companies that provide goods and services for year-end celebrations. Xie Yu reports from Shanghai.

Back-to-back year-end holidays boost party stores' and catering businesses' sales, and create cash flows for big restaurants and luxury hotels in Shanghai. Yang Zhenhua is having his busiest days of the year with Christmas, New Year and Spring Festival. His small party store in Shanghai's Biyun international community is crammed with balloons, candles, streamers, banners, tableware, toys and gifts.

"Here we go," the 34-year-old says, climbing a ladder to retrieve a bright yellow papier-mache rooster.

"It's called a pinata. You fill it with candies and chocolates, and then hang it high in the party room. You break it with a stick, and candies shower down like rain. Kids just love it."

The Shanghai native gave up his lucrative interior decoration business and opened the JaJaJa Party Shop in 2009. His business has been growing vigorously, and he plans to open a second party store in western Shanghai.

"From late October until the following February are the golden days," Yang says.

"Thanksgiving, Christmas, New Year, the Chinese lunar new year ... It's the party season."

He can earn more than 200,000 yuan ($32,250) per holiday, he says.

Yang has also taken his store into cyberspace and his online sales are booming.

Items available in JaJaJa cost between 6 yuan and hundreds of yuan. The company also offers party services, including venue decoration, entertainment and food preparation. A private party costs from 200 yuan to tens of thousands yuan.

"It depends on the customers' requirements," Yang says.

"If you just want simple party decorations, we charge only 200 to 300 yuan. But if the customer wants more entertainment and food, it may cost much more."

Yang and his colleagues just organized a private party with a "Lightening McQueen" (a racecar who is the hero of the computer-generated film Cars) theme for an Indian client.
