I have tried to refine the information on these eight Chinese movies of interest. The first movie that might be a Charlie Chan movie is listed below. There is very little information on it to be found. However, I think the title is now probably more accurately translated. It seems to refer to some particular person's body and the person is named 'Lan Guifei'.

I have more information on this next film. I have even laboriously done a character-by-character translation of the plot summary and think that this new translation of the story is approximately accurate, though a native speaker of Manadarin should confirm this.

SPOILER ALERT! SPOILER ALERT! SPOILER ALERT!

赵家古墓被盗，失物包括一件价值连城的珍珠衫。陈查礼从国外归来，正与女儿住在赵家，于是参加了侦破工作。古墓中发现一粒子弹，经查是大同俱乐部保镖许得胜用的。赶去才发现许已被杀，随即发生一系列谋杀案。陈查礼暗布圈套，深入盗窟。美娜接到父亲无线电信号，带人将盗贼抓获，并追回失窃珠宝。赵家为陈查礼庆功，同时为珍珠衫未被追回而遗憾，陈查礼却不慌不忙地让美娜拿出了珍珠衫。

The Zhao family ancient grave is robbed, and one of the lost objects is a priceless shirt with pearls. Having returned from overseas, Charlie Chan is staying with his daughter in the Zhao family home, and therefore participates in the investigation. In the ancient grave, a bullet is found, used by a bodyguard, Deisheng Xu, at the Datong Club. Chan hurries away only to discover someone has already been killed, and there is now a series of murders. Charlie Chan sets a dark cloth trap in the robber’s cave. Meina receives a radio signal from her father, which leads to the capture of the thieves and the recovery of the lost jewellery. Jiawei Zhao congratulates Charlie Chan, but at the same time expresses regret that the shirt with pearls was not also recovered. However, Charlie Chan isn’t nervous. He lets Meina produce the shirt with pearls.

Again, I have a fair amount of information on this next film and I have tried to hammer out a more comprehensible plot summary via laborious character-for-character translation.

SPOILER ALERT! SPOILER ALERT! SPOILER ALERT!

A thief uses a secret stealth (invisibility?) method to commit a crime, and Charlie Chan helps Detective Zhang solve the case. —
Charlie Chan and his daughter, Meina Chan, are hired by Detective Zhang to help investigate a case of an ongoing series of weird thefts. Chan’s friend, Xiao Yougin, also gives assistance. One day, Chan and his daughter are invited to attend a large lavish birthday banquet, where this bizarre sort of theft happens again, for although valuables were put in a safe, the precious jewellery vanishes into thin air. A servant is also killed. Jia Yi and Lu Shaoting, two suspicious individuals, were in attendance at the banquet, but there is no definite evidence of who is guilty. Jia Yi’s girlfriend, Zhou Yuehua, behaves very strangely, but it is not clear why. Qian Manyun accidentally discovers that Zhou obtained jewellery that was very like the jewellery that she herself lost. Chan and his daughter go about investigating, but almost run into danger. Afterwards, Charlie Chan invents spectacles that may possibly reveal the stealth technique used. However, he must wait to use the spectacles when they cannot be found, so the case becomes deadlocked. Xiao Yougin is also extremely disappointed. Then, Meina thinks of an idea. The daughter sets up a snare for the two people, finally causing the stealth robber to walk into the trap.

Here's another one with very little information to be found. Like the film from 1937, it may not be a Chan film.

Manna continues to drive to go to the villa, but Cima Ming ambushes her first, blocking the car in the road, and again strangling Manna. He then pushes the car with the body inside down the hill. Charlie Chan learns that Manna is missing, thereupon the company understands that a case has been reported to the police department. At the time when Ming signalled police, one white chrysanthemum was in her overcoat, therefore the suspicion is put on Charlie, suggesting that he is the actual murderer. Charlie deliberately lets Ming hold the misconception that Manna is still alive, causing him to visit the car at the scene of the murder. Then a group of police arrive to take him into custody.

The great detective Charlie Chan meets a wealthy member of the gentry, Guangzhou You, and investigates the riddle of the suicide of his elder brother, Guangcai You, who jumped from a building. Charlie, in the company of daughter Meina, is given broad latitude to investigate, but only at this point begin the real murders of the villains. Charlie suspects the wealthy businessman, Wu Huaide, so dispatches Meina on a secret investigation. Meina tracks Huaide’s female secretary, Dong Lizhu, to the train station, and sees her handing over a leather suitcase to a mysterious man. Charlie and Meina trace this to a wooden shack in the suburbs. Seizing the leather suitcase, they find it full of counterfeit money. To defeat Huaide’s plot, a plan is offered to the police — the backroom of the counterfeit money group secretly protects its leader, so whoever knows the group’s leader can unexpectedly to make first move and get control. To get Huaide to return to the nest of thieves now, Meina gets on Lizhu's trail to follow her back to the criminals’ hideout. She is captured by a henchman and taken into the cellar, but fortunately Charlie arrives in the nick of time. It is disclosed that the primary brain behind the operation is the banking tycoon Jin-Yibai Chuan. However, the police also arrive at the counterfeit money group hideout and catch the whole lot in a dragnet. Yibai Chuan and Huaide die under the bullet.

And here's the last one. Again, very little info online, but the title confirms that this is a Charlie Chan film to be sure.
