The deal was confirmed by Chelsea on Wednesday:
The club's official website provided an accompanying statement. "We thank him for his service and wish him well in China, where he will be coached by another former Blue, Dan Petrescu," read a section.
According to Darren Lewis and Adrian Kajumba of the Daily Mirror, the Blues will receive around £25 million for the Brazil international.
The news will disappoint Chelsea fans, as Ramires has shone in previous seasons and is in the prime of his career at 28 years old.
During his career at Stamford Bridge, Ramires won plenty, including the UEFA Champions League, Premier League, Europa League, FA Cup and League Cup. He made a total of 251 appearances for the Blues, scoring 34 goals in the process.
The most memorable one of the lot was this stunning lob against Barcelona during a Champions League semi-final, a strike that eventually propelled Chelsea to their first-ever European Cup triumph:
Ramires arrived at Chelsea from Benfica for £17 million in 2010, per BBC Sport, and steadily developed into one of the league's most versatile midfielders.
However, he has been limited to only seven starts in the Premier League this term and has been used sparingly by the Blues over the past 18 months, according to WhoScored.com.
Former Chelsea player Petrescu is coach of Jiangsu, and Ramires follows compatriot Paulinho to China. Paulinho departed Tottenham Hotspur to join Guangzhou Evergrande in the 2015 summer transfer window.
The Brazilian has played a vital role in the Chelsea squad, and he will not be easily replaced in the short term.
Ramires was well aware of his role in the team and has produced excellent performances when operating in a Blues shirt.
However, China offers a new challenge for the player; John Obi Mikel usurped Ramires in the pecking order under interim coach Guus Hiddink, and his outlook at the Bridge was beginning to look increasingly bleak.
