What are the six-character mantra of Buddhism?

There are two ways to pronounce the information found, and there is only one six-character mantra: 1:

Mi (An), Ma (Ma), Ni (Ni), Ba (Ba), Mi (Mei) and Hong (Hong).

2:

Hum (not ng), (mā), (nρ), beep (bēi), microphone (mēi) and bang (hòng), the second type is read by many people.

However, the mantra lies not in pronunciation, but in meaning. You can read it three times if you understand the meaning.

Tantric Buddhism and Tibetan Buddhism in China also read Guanyin Bodhisattva and Amitabha. They don't recite the name of Guanyin Bodhisattva, but recite the six-character Daming Mantra, the six-character Daming Mantra or Guanyin Bodhisattva. The six-character Daming mantra is to recite "Fantuo Lihua" (Lotus), which translates into Chinese meaning "Keep your body and mind like Fantuo Lihua" and never forget it. In this world, it is not polluted by secular laws, which is the real meaning of this mantra. This spell always reminds yourself and others not to be polluted by this world. What do you mean by this spell! This is the majesty of Miaobao. Therefore, the solemnity of Miaobao is embodied in the name of Buddha and Bodhisattva, in the teaching methods of Buddha and Bodhisattva, and in the six-character Daming mantra of "Ba, Ma, Ni, Ba, Mi and Yi".

It seems that 1 one is Chinese reading and the other is Tibetan reading.
