Today is an in-depth tour of DC. After walking a lot of places, I have to divide it into two stickers to barely finish it. Let's talk about the morning: ② In the morning, the bus from New York to ⑨ DC froze for one night, and arrived at ◎ Union Station ③ ④ at 8 o'clock and departed for ⑨ United States Capitol Building. In theory, you need to make an early appointment to visit, but today there may be few people, and I almost didn't even need to queue up to let me in. ⑦ Follow the free tour to visit the interior of the Capitol. It is still quite luxurious Jo ⑨① out of the Capitol. I went to the ⑨ Library of Congress on the side. This place may be relatively niche, but definitely worth a look, the interior is quite gorgeous! And it’s free too.
