Ai Fukuhara was born in Miyagi, Japan, in 1988. She picked up a paddle at 3 and won a national title at 5. Because Japan lacked high-level sparring partners, from age 10 she trained long-term in Liaoning, China — hence her perfect northeastern dialect.

Fukuhara is the Japanese athlete Chinese viewers know best. Her round face, quick tears and northeastern-flavoured Mandarin made her enormously popular. At the 2008 Beijing Olympics Chinese fans cheered for her; when she cried after losing to Chinese players, they felt for her. Her nickname: "porcelain doll" — pretty, cute, easy to crack.

She stayed close to the Chinese team: calling Wang Nan "Sister Wang", and later marrying the Taiwanese player Chiang Hung-chieh. After retiring she remains active in Sino-Japanese exchange.

Asked whether she is Japanese or Chinese, she once smiled: "I'm Japanese, but half my youth was spent in China." Sport knows no borders and friendship crosses languages — that is why China loves Ai Fukuhara.

Fukuhara Ai (1988- ), Japanese table tennis player, enjoys enormous popularity in China for her cute looks, tendency to cry and fluent Northeastern dialect - nicknamed the "Porcelain Doll" by Chinese fans.

Her China connection: she started playing at age 4, came to China for training with her parents in 1994, and formally trained in Liaoning from 1998, living and practising in China for years. Her Dongbei dialect, learned from Liaoning team coaches and teammates, is so authentic and adorable that even Chinese audiences marvel.

Career: one of the most successful Japanese women table tennis players ever. At 15 she was Japan youngest Olympian at Athens 2004; she led Japan women to silver at London 2012 (Japan first-ever Olympic medal in table tennis) and bronze at Rio 2016.

"Ambassador of Sino-Japanese friendship": she trained alongside Chinese teams from childhood, forging deep bonds with Wang Nan, Zhang Yining and Liu Shiwen. She cried in defeat and laughed in victory; her frank, lovable nature made Chinese fans treat her like their own daughter.

Her China sentiment: she retired in 2018 and later settled in Taiwan, interacting with fans in Chinese on social media. Saying "China is my second homeland" moved countless Chinese fans.

Lesson for learners: the appeal of her Chinese lies not just in correctness but in affection - a Chinese with heart. Her example shows the best way to learn a language is to truly immerse in a culture and make friends.

A warm detail: she decorated her paddle with her own drawings, hid to cry after losses, then came out smiling after teammates comforted her - these images made Chinese audiences remember a "real" athlete. She proves sport knows no borders, and neither does friendship.

A special feature of her Chinese: the Northeastern accent was not "learned" but "lived" - her whole girlhood was spent in Liaoning. That is why her Chinese feels so natural: language is never knowledge but life itself.
