I personally feel it's very good. You won't see such a detailed, informative, sophisticated, and complete tour in other cities. The Northeast Marshal's Mansion (Zhang Xueliang's former residence) is especially impressive, especially the residences of Zhang Zuolin's wives, each with its own unique charm. There's also the Grand Green Building, where Zhang Xueliang, his wife Yu Fengzhi, and their children lived. There's also the story behind the silver dollar, the Tiger Hall, the Little Green Building, and Zhao Yidi's Little White Building. All of these are stories. In short, they're all worth the money. It's a worthwhile trip! The pictures are just part of the story. If you look closely, it'll take at least 2.5 hours.
