Mention the magnificent museum that seems to stand at the pinnacle of American art, elegantly situated beside the bustling Fifth Avenue, just a leisurely stroll from Central Park, where one can soon encounter this cultural feast. The ticket price circulating online is said to be $25, but upon visiting, one realizes that it operates on a warm donation system, with a minimum of just $1 to enter this hall of art, and generosity has no upper limit. Even more delightful is that before entering, one can obtain a detailed guide map for free. Unfortunately, I couldn't find a Chinese version after searching for a while. For someone like me, who is fairly fluent but not proficient in English, I had to rely on my enthusiasm and curiosity to take a quick glance at this ocean of art and return fully satisfied.
