The testimony of Sun Yang and his mother was not fully expressed due to repeated interruptions by the opposing lawyer and problems in translation, which affected the trial of the case and left them with great regret.
Sun Yang's mother shed tears several times in the notarization meeting and subsequent interviews, filled with sadness and love for her son's hard work for more than ten years, and even treated her son unfairly. Presumably, as a mother, what happened to her son in these 400 days made her extremely depressed. However, at the hearing, she did her best, but failed to do so. This also became the fuse of her emotional outburst. She sobbed several times and finally complained that "they didn't give me a chance to make it clear".
To sum up, the word "they" in Sun Yang's mother's "they didn't give me a chance to make it clear" should mean that the lawyer of the other anti-agitation organization interrupted her explanation many times, and it should also mean the judge of the notary office. After all, it is one thing to always interrupt testimony, and the judge's inaction in the face of testimony also accounts for some factors, not to mention stopping before the testimony is finished.
