Here is the complete translation of the text as per your request:
"Han Mingzhe knows Qin He!"
Leng Mochen stated firmly, though he had suspected it before.
It was only recently that it became confirmed.
At that time, after Qin Xin arrived in Beijing from North City, she joined Zheng Huanxue's company.
Earlier, at Li Si's wedding banquet, Nie Xiuwei had brought a surgically-altered Qin Xin to the event, gaining entry through Zheng Huanxue.
Since Zheng Huanxue and Han Mingzhe had met abroad and become a couple, it was impossible for the two of them not to know Qin He privately.
Additionally, Qin He had known Nie Xiuwei long before. It was unclear why Nie Xiuwei did not mention Qin Xin to Qin He at the time.
Or perhaps he didn't yet know about Qin Xin's true origins back then! It may have come to light later by coincidence!
Han Mingzhe and Qin He may have been introduced to each other by Nie Xiuwei, for all we know.
