To answer many viewers who thought "Sword of the Assassin" looks like of Chinese origin, it is because IT'S COPIED from Chinese origin. In Vietnam "Sword of the Assassin" is widely known to have plagiarized from several Chinese and Korean movies. This is the same movie called "Blood Letter" but the filmmakers switched the title to "Sword of the Assassin" after Vietnamese social media exposed the plagiarism. It's a big scandal in Vietnamese language media and social media. Some Vietnamese language links: Youtube video "Vietnamese American movie director plagiarize more movies"

Now you know the reason why everyone said how "Chinese" the movie is. Historical influence is no excuse for modern plagiarism, look at Korean movies they had same historical influence but didn't plagiarize and developed a unique Korean cinema. The director had a history of plagiarizing foreign movies and claiming author, particularly he was the first filmmaker investigated for plagiarism by Vietnamese cinema regulators and found to have plagiarized "Shattered"

The Vietnamese subtitles in the "Sword of the Assassin" expose video say after the director was found guilty for plagiarizing "Shattered", he now copies from different movies and combine to make it harder for the public to find out original source.
