Chinese pinyin l m: o chá n ω zh m: n ω.

Note: there is no light tone here, only tone sandhi.

Factory, originally three tones, but because the length is also three tones, the "factory" should be changed to two tones.

Ps: When spelling Pinyin, we should always pay attention to the following questions.

1) Don't confuse the front nasal sound with the back nasal sound. Such as in and ing, en and eng.

2) Don't confuse flat tongue sounds with sticky tongue sounds. Such as children and delay, thinking and the world.

3) Tone symbols must not be misplaced. For example, Hui's fourth sound is wrongly marked on the letter U, but it is actually marked on the letter I. ..

4) Words with tone sandhi, such as "178", should be marked according to the original tone, and the tone sandhi should be changed when reading. For example, "one" is originally a sound, but it should be pronounced as a second sound.
