Eakvixay Tran is a Lao student studying economics at Tsinghua University. He says he was amazed by how China preserves ancient structures, like the Great Wall, and how people infuse culture into their daily life. "Even though almost every Chinese knows what the Great Wall looks like, they still choose to go back there even annually, like on their anniversary or their birthday," he said.
