If the police have determined the motive of the kidnapping, then the investigation will move forward quickly. The last statement from the police was that Mr. Lu did not know what the motive was.
There are so many possibilities. Until they uncover the motive, at least they can continue to try to track down the perpetrators.
Was this a "scam" directed towards Wanzhen? This is just one possibility. This is only a thought of mine.
Below are excerpts from news articles concerning different scams directed towards students from China in schools in Canada:

"The victim is then manipulated into staging their own kidnapping. To save the family member – who is actually completely safe – the student is told to go into hiding and fake a kidnapping video."
"Victims are asked to rent a hotel room and avoid any interaction on social media or with the police, under threat of retaliation against their family in China."

"It started, Zhang said, when his daughter got a call at her rental home near campus. It was a man's voice, purporting to be from the local Chinese consulate.
The man said her personal information had been stolen, used to open a bank account linked to illegal dealings and that Interpol was looking for her.
The caller told her to go into hiding and cut off communication with anyone she knew. Otherwise, the criminals who stole her information could track her down and hurt her family."

"Police said the scam usually targets female Chinese students abroad. It starts when someone calls the student and tells her Chinese police want to arrest her, or that Chinese police need her help."
"The scammers get the victim to record videos that make the kidnapping look real. They use the videos to extort money from the family. The victim is told to hide from Canadian police."
