Question: When did the dynasty that Ji was born during start? Passage:Jiang Ji (died 18 May 249), courtesy name Zitong, was an official and military general of the state of Cao Wei during the Three Kingdoms period of China. Born in the late Eastern Han dynasty, Jiang Ji started his career as a low-level official in his native Yang Province before becoming a subordinate of Cao Cao, the warlord who controlled the central government towards the end of the Eastern Han dynasty. After the end of the Eastern Han dynasty, he served in the state of Cao Wei through the reigns of the first three emperors – Cao Pi, Cao Rui and Cao Fang – and held various appointments in the military before rising to Grand Commandant, one of the top positions in the central government. During his service in Wei, he was known for being candid in giving advice to the emperor on various issues, including consolidating power, halting labour-intensive construction projects, and officials' abuses of power. In February 249, he joined the regent Sima Yi in staging a successful coup d'état against his co-regent Cao Shuang, but died from illness a few months later.

question:
Question: Was the stadium where McClean scored a goal in snowy conditions built prior to 2000? Passage:McClean made his first start for Sunderland in their 1–0 victory over Manchester City on 1 January 2012, and scored his first senior goal for the Black Cats in a 4–1 win against Wigan Athletic two days later; on 8 January, he scored and assisted Sebastian Larsson in a 2–0 win at Peterborough United in the third round of the FA Cup. McClean provided the assist for Stéphane Sessègnon's opening goal in Sunderland's 2–0 victory over Swansea City on 21 January, and got another assist in the equalising goal for Fraizer Campbell in the next round of the cup against Middlesbrough on 29 January. Ahead of the replay for that fixture, Middlesbrough manager Tony Mowbray used McClean as an example for young players to follow. McClean turned provider again in Sunderland's 3–0 victory over Norwich City, assisting Sessègnon's goal, then scored the only goal in a win over Stoke City on 4 February in snowy conditions at the Britannia Stadium. A week later, he opened the scoring in Sunderland's 2–1 home loss to Arsenal after Per Mertesacker injured himself. On 23 March, Sunderland announced that McClean had signed a new contract intended to force him to stay at the club until the summer of 2015. A day later, he helped them to a 3–1 victory over relegation-threatened Queens Park Rangers by assisting the opening goal for Nicklas Bendtner and later scoring by himself. McClean won Sunderland's Young Player of the Year Award, at the end of the 2011–12 season.
