I thought he’s just a Weeabo but it’s looking more like he’s a real traitor. These pictures didn’t happen over 2018 but a span of few years so it’s not a coincidence. Here is a more detailed summary from online post by Dabosil:

“Firstly, the incident is not over one image. Also, it’s true that the fact that this came out at such a time is suspicious. However, as far as we know, a netizen first spotted the photo with the Japanese Rising Sun Flag. Of course, this does not eliminate the possibility of other forces lurking behind. However, this fact in itself does not erase anything ZZH has done.

Composite Timeline: (This is also highlighted in several articles)

2017-ZZH shares a photo of a car with the Japanese Rising Sun Flag.

*From the internet: The Japanese Rising Sun Flag is representative of the Imperial Japanese Navy, and was used when Japan colonized the Korean Peninsula and invaded and occupied China.

2018-On China’s NATIONAL DAY, ZZH shares (rough translation), ‘On this nationally celebrated holiday (I) of course have to go back into my homeland’s embrace. During the National Day Period (I) won’t go anywhere. (I’ll only be) at home, enjoying the warmth of my homeland (country). Happy Birthday, I love you, China’, though the photos attached indicate he is at Ginza,Tokyo.

2018-ZZH takes photos outside of Yasukuni Shrine

*The Yasukuni Shrine commemorates the Japanese who have died in wars from the 19th century, including World War II

And more details of controversial visits from Japanese Emperors/Prime Ministers are here:

2019-ZZH visits the Nogi Shrine to attend his friend’s wedding

*Nogi Shrine is named for Nogi Maresuke, a prominent Japanese general who was heavily involved during the Sino-Japanese War invasion of China (such as the Port Arthur Massacre).

ZZH takes a photo with Ratna Sewi Dewi Soekarno, also known as Dewi Fujin in Japan

Her husband launched ‘The September 30th Incident’, also known as Gerakan 30 September, comprising of an anti-Communist massacre, including many Chinese.
She herself is also known for displaying anti-Chinese comments, which means she is obviously unfriendly when it comes to China. Additionally, during the 2017 Asian Games, it was found that the APA hotel guest rooms displayed books that denied the existence of the Nanjing Massacre and Comfort Women (this itself is a huge controversy internationally). She was invited on a television show where she excused the incident in terms of ‘free speech’.

Therefore, ZZH’s photo with her is….controversial to say the least.

Of course, you can say that many of them may be coincidences. However, there is also his hypocritical statement:

In the public apology ZZH sent out, he apologizes for his naivety (towards his knowledge of the local culture and history).
However, his statement was attacked, because:

Part of Zhang Zhehan’s public persona has been his love of reading. In fact, his fans compiled a booklist of all of the books he has read (that they know of).

Two of the books listed in the booklist, ‘Kafka on the Shore’, and ‘Killing Commendatore very specifically talk about the Yasukuni Shrine and Japanese Revisionism.

This to many people is yet another offending factor, that when in light of public persona ZZH’s love of reading is marketed and where he shows apparent ignorance for landmarks such as the Yasukuni Shrine he professes his naivety.

–

The first photo was dug out in July, In response, ZZH deleted the post, though he then shared a Weibo post insinuating the netizens were being nosy and continued forth with a lawyer’s statement warning those who spread malicious rumors to stop at once. Additionally (this part is a bit hard to translate) but on the post’s tail (that is, the subheader to the post which lists the time and date and from what device the post is posted, in which you can add a phrase) it says ‘Tidy up (them) one by one’.

As for the other extra photos such as the apparent Nazi Salute, sitting on the tombstone of a revered Chinese figure, inappropriate gestures etc.-those are just extras, they’re not the main point, I think some of them could be excused and some are also unclear. The focus is on the shrines AND his attitude.

That’s about it for now.

Edit: By a general scope, what does comparing ZZH to Kris Wu say about viewers as a whole? Celebrities, especially in the East (and in China and Korea where actors, singers, and entertainers are mixed in with the concept of idols) are supposed to be role models, and represent who you aspire to be like. The increasingly lowering standards for celebrities is concerning. The comparison does not erase anything.

Honestly, this is not just about politics.

*Also, again, this is just about ZZH himself, so let’s not relate it to Word of Honor or any of his dramas. ZZH has struck a very sensitive nerve, so I highly doubt he will come back in the public light.”
