As the earliest relics of star formation episodes in the history of the Universe, the most massive galaxies are the key to our understanding of the evolution of the stellar population, cosmic structure, and SMBHs. However, the details of their formation histories remain uncertain. We address these problems by planning a large survey sample of ultramassive galaxies ($z\le0.3$, $|\delta+24^{\circ}|<45$\deg, $|b|>8$\deg), including 76% E, 17% S0, and 7% S brighter than $M_K\le-27$ mag (stellar mass $2\times10^{12}
