The method of recording years using Heavenly Stems and Earthly Branches originated in China. Since ancient times, China has had ten Heavenly Stems and twelve Earthly Branches. The ten Heavenly Stems are: Jia (甲), Yi (乙), Bing (丙), Ding (丁), Wu (戊), Ji (己), Geng (庚), Xin (辛), Ren (壬), Gui (癸); the twelve Earthly Branches are: Zi (子), Chou (丑), Yin (寅), Mao (卯), Chen (辰), Si (巳), Wu (午), Wei (未), Shen (申), You (酉), Xu (戌), Hai (亥). The method of recording years using Heavenly Stems and Earthly Branches pairs a Heavenly Stem with an Earthly Branch in sequence, with the Heavenly Stem coming first and the Earthly Branch coming second. The sequence starts with Jia (甲) for the Heavenly Stems and Zi (子) for the Earthly Branches. For example, the first year is Jiazi (甲子), the second year is Yichou (乙丑), the third year is Bingyin (丙寅), and so on. After reaching Guiyou (癸酉), the sequence returns to Jia (甲) and starts over, i.e., Jiaxu (甲戌), Yihai (乙亥), and then the Earthly Branches return to Zi (子) and start over, i.e., Bingzi (丙子), and so on. It is known that the year 2017 is the Dingyou (丁酉) year. Therefore, in the year when the People's Republic of China celebrates its 100th anniversary, i.e., 2049, it will be the \_\_\_\_\_\_ year.
