The consumer cheer unleashed by Sunday's 11-11(or double-eleven) Singles Day online shopping festival will likely extend till New Year's Day in China, coasting on the growing popularity of non-religious Christmas-time celebrations, industry insiders said.

Increasingly, even Chinese consumers, not just the global markets, are buying Christmas items produced in Yiwu in Zhejiang province, East China.

Also known as "Santa's Workshop", Yiwu has seen a spike in sales of smaller varieties of Christmas decoration items this year as Chinese consumers prefer them to big-ticket items that are popular elsewhere.

On Yiwugou, an online retail platform of Yiwu manufacturers, the top five domestic sales items this year are fake berry plants, snowman table decorations, gift cards, snowmen made of lights, and balloons.

On Taobao, the online marketplace of Alibaba, the top three Christmas-themed items are socks, LED lights, and window stickers.

"Smaller Christmas gifts like headbands and socks are preferred by domestic buyers, compared to overseas buyers who prefer large plush Santa toys and Christmas trees," said Zhu Guohua, a Christmas gift store owner in Yiwu who has been in this business for about 15 years.

Zhu said overseas buyers visiting his store as well as other stores in Yiwu have increased by 5 percent this year. He attributed the rise to buyers' eagerness to complete purchases before prices rise further due to higher US import tariffs on Chinese goods.

Zhao Ping, director of research at the Academy of China Council for the Promotion of International Trade, said unlike in overseas markets where Christmas is a religious festival and a time for family reunions, consumers in China tend to use the year's last week to inject some cheer into the dim winter by buying low-value decoration items.

Hence, Christmas trees and large plush Santa products, which are relatively costlier and require more time to install, are not popular in the domestic market as they are elsewhere.

"Christmas-time celebrations are more commonly seen among younger people who prefer to hang out with friends and exchange gifts," said Zhao.

Unsurprisingly, that entails outdoor activities, and, from late October, the sense that Christmas is nigh drives consumers to restaurants and malls.

Zhao said: "In recent years, Christmas has been a great sales season for Chinese consumers, especially those who prefer overseas brands. However, Christmas sales are less popular than Singles Day sales and the new year sales.

"Moreover, Chinese consumers are getting more rational in their purchases. They know there will always be a next sales season. They are also less price-sensitive as their disposable incomes have risen in recent times."

So, businesses such as cosmetics giant Yves Saint Laurent are enhancing their marketing, branding and promotional activities around Christmas, focusing on things like limited-edition collections, said a report from consulting firm Frost & Sullivan.

YSL's Sparkle Clash lipstick collection was an instant sellout during the 2016 Christmas season, and remained on top of the recommendations of social media influencers.

The social media boom in China in recent years has sparked a rise in digital channel advertising by brands around Christmas, market insiders said.

Zhang Yang, 26, a Beijing-based film producer, said she buys makeup and home appliances after watching short videos on an app called Douyin, which is known as TikTok in overseas markets.

Zhang said: "I follow several social media influencers on Douyin. They specialize in makeup tutorials, cooking tutorials, and pet products. I tend to buy some of their recommendations and those receiving online reviews.

"I can see Christmas products are having increasing visibility on Douyin. It's a surprise - I mean, there are still two months to go before the holiday."
