I go check her facebook only realized it is the school just near my place...
Didn't expect such thing to happen in school and where's the support from the school for the teacher?

Surely this will be the talk of the town this week.

Tldr ... reli... summary

Don't bother, it's delusional rambling (and I meant that nicely). It's like you take the victim mentality you have here in /k but cranked up all the way to 11. I'm amazed if she's still working at the school after such posting.
Tried to extract some below, please do not take any of them seriously. I tried to glean some sense/backstory and couldn't find any.
The one she named the most is Teh Lay Cheng (school psychiatrist?) & Chin Pei Pei (ex-husband?). From that post, the allegations are:
- Bullied & killed her friend Lim Mei Ling in 2017
- Caused another friend Lim Ai Mei hemorrhagic collapse and dystocia in 2007
- Harmed her godfather Leow Hup Heng
- Killed and set trap to her friends from Perak, Cai Hong and Jia Hui
- Wanted to make her die of a mental illness in the mental hospital
- Claimed to other people that she said Looi Chiang Meng medicine would kill people (eventhough she's taking it)
- Threatening her elder brother, sister and younger brother and taught her daughter to make illegal investments and debts, and wanted her daughter to become a prostitute. (She has a daughter!?) 
- Deliberately pushed her mother down while she was alone at home and made her mother unable to live (paralyzed?)
- Cooperated with her brother & brother's relatives to create a real car accident and hit her father Chew Teo Eng until he got the insurance compensation of RM180,000 (?)
- Named her brothers to be the EPF's recipient (of father?) and excluded her.
- Setting a trap for her brother to owe a huge debt and deliberately made him an alcoholic and controlled his soul(?) and wanted to kill her.
- Ch'ng Soon Lee and Ng Chew Leng who harmed her (who?)
- Along with other people (her siblings?), poisoned her father via his meals for the insurance money.
- Turned a thousand people to hunt her (and a thousand innocents have died due to this).
- Deceived her daughter into engaging in more than 30 illegal gambling and illegal investments and owed a debt of 10 million
- If daughter debt not repaid, they would take her daughter and go to the Philippines to work as a prostitute.
- Planned to kill her sister then her (based on her friend who hired nearly 2 thousand assistants for investigation)
- Planned to kill retired JPNPP director in Hatyai Thailand
- Based on her grandpa, Teh Lay Cheng slept with more than a thousand men for money.
- Teh Lay Cheng herself killed her parents when Teh Lay Cheng was very young.
- Teh Lay Cheng was going to marry Dato Tan Lai Hock in order to rob all property of Dato Tan Lai Hock (claiming via Dato laying a hand on her while drunk, never happened)
- Helped by Dr Ng to kill her mother in  Penang psikiatri hospital
- In 2002, Teh Lay Cheng sold her as a prostitute for 1 million during the vacation, was studying at IPDA Teachers College, and they wanted to sell her to the Philippines by boat.
- Created false evidence to harm Lim Guan Eng
- Ordered more than 20 police officers to beat me to death
- Bribed lawyers, police officers, and doctors kill her parents and hunt her down. The killer also used a chair to beat her parents from head to toe, brutally tortured mother and father every minute until they died.
Another pair named in bottom half is Chew Keng Beng and Chew Hock Kiang (her siblings?)
- Involved with above to kill her parents and planned to kill her hsister for insurance money.
Bottom half comes Master Ong Q Leng and Sim Swee Heng
- In 2006 and 2007 five uncles chased her together to kill her.
- Had a spell (Christian & Buddhist spells) casted on her to kill her and those friendly to her (has killed more than 10 thousand innocent people)
- Killed her grandpa because 'grandpa shared the big bun with me, grandpa ate half of the big bun' (what?)
- Asked the ghost outside the gate SJKC Beng Teik Pusat to do something to her.
- Were involved in various criminal activities, including Internet fraud, illegal investment, various illegal gambling and other illegal activities, and involved multiple lawyers, multiple rogue police officers, and rogue doctors.
- Activities include buying and selling organs on the black market, selling young girls to be prostitutes.
- With help of Dr. Ng, helped Lim Hui Ying to harm Lim Guan Eng (whaaattt?)
- All the corruption against Lim Guan Eng were caused by the use of psychology by Teh Lay Cheng and Master Ong Q Leng taught to Lim Hui Ying.
Some of her claims:
- She has 300 nieces and nephews in Japan
- 20,000 relatives from all over the world
- 2,000 assistance hired to do investigations to help clarify her story with proofs
- Her grandmother Chuah Qing Liang gave the inheritance of 500 acres rubber plantations to the government to support Lim Kit Siang.

That's 1 hour of my life spent trying to unfurl the mind of someone obviously broken. 

Tak paham, based on translation, parents and school macam tai chi to the teacher?

"The school is actually very sad. They have worked hard over the past many years to arrange various things, but the teacher's personal behavior was ruined and the reputation of the school was damaged because of false speculation on the Internet."

Mental health issue isn't the problem.. It often can be managed properly with support. Those with mental health issues should be able to earn a living.

It's the rudeness of students, ignorance of school, and death
threats from parents are the trigger point for her.

Headmaster needs to manage this ASAP.

she is hallucinating again? : https://www.facebook.com/profile.php?id=61554591406389
