Song Ji Hyo and Gary are the subjects of the largest portal on China's Sina. The "Running Man" stars, who are known as the Monday Couple, were featured on the main page of Sina, due to the popularity of their portal.

On January 21, the Korean outlet Sports Chosun reported the milestone, which is attributed to the success of both celebrities within mainland China.

The portal, which was promoted through Sina Entertainment News, includes highlights from "Running Man," where the Monday Couple is regularly paired together, during challenges.

"[This is] one example of the local popularity and awareness of 'Running Man' stars Gary and Song Ji Hyo," said a representative for China's Hallyu Contents. "Their popularity [in China] along with Kim Jong Kook is inexplicable and beyond imagination."

"Running Man" recently wrapped up filming in Beijing, where Song Ji Hyo was paired with Song Joong Ki, a former fixed cast member of the variety show, who is preparing for his K-Drama comeback in the highly anticipated action drama, "Descendants of the Sun."

Song Ji Hyo was also cast in the Chinese version of the scripted relationship program, "We Got Married," where she will appear as the on-screen bride to Taiwanese actor, Chen Bolin (Twenty Once Again).

While Monday Couple fans may have been dismayed by news that the 34-year-old actress would appear on "We Got Married," supporters of the on-screen pair continue to demonstrate their support for "Lonely Night," the recent single released by Gary, whose corresponding music video features Song.

"Lonely Night" performed well in Korea and dominated Baidu Music, a Chinese site and real-time chart.

Meanwhile, Song will to the silver screen in the upcoming Chinese film, "Super Express."
