Up to now, Wood has published more than 60 diaries, and he still updates the diaries frequently on social media websites. In his first diary, he mentioned, "News is going around about a bad cold virus in Wuhan, but I feel worlds away from me and few people wear masks in public."

He recorded in his diaries that thousands of medical workers from different provinces and cities went to Hubei to help with the anti-epidemic (抗疫). Restaurants and shops were closed down, while supermarkets checked people's body temperatures. And community workers across the country took strict action, asking people to stay at home and helping the old buy daily necessities.

"People in some countries said these measures could cause panic among the public. However, my experience in China shows these efforts are useful and effective, which finally removed people's fear," Wood said.

Wood's diaries soon attracted the world's attention. Over 10,000 people left him messages online, and he was interviewed by Canadian CTV which later showed his diaries on its website.

"I also received greetings from my family and friends in Canada. They said they were inspired by the efforts the Chinese have made," he said. "People from some countries thought the Chinese overreacted, and that the Chinese government had overdone in epidemic prevention and control. However, since more countries and regions have been infected (感染) by the virus, more and more people came to realize how proper and important China's control and prevention measures are."

Wood is working with the New World Press, which plans to make his diaries a book named The Invisible War. In this book, he hopes to share China's anti-epidemic experience with more people across the world so they can build confidence to fight against the virus.
