How to write Russian Chinese mainland?

Learning Russian begins with pronunciation.

The vocal organs include respiratory organs, larynx, vocal cords, pharyngeal cavity, oral cavity and nasal cavity. When the airflow exhaled by the lungs passes through the throat, mouth and nasal cavity, it is controlled by different forms, vibrates and sings, forming speech.

The function of respiratory organs is to supply the airflow needed for pronunciation.

The vocal cords in the larynx are important organs to form sounds. When the glottis are closed, the vocal cords vibrate when the airflow passes, giving out musical sounds, vowels and voiced consonants, and the vocal cords also vibrate. When the consonants are voiced, the glottis open, and when the airflow passes, the vocal cords do not vibrate.

The oral cavity includes lips, tongue, teeth, gums, hard palate, soft palate and uvula. Teeth, gums and hard palate are static when pronouncing, and they are the fulcrum of the activity of the vocal organs. Tongue is divided into tip of tongue, front part of tongue, middle part of tongue and back part of tongue. Tongue is the most flexible pronunciation organ in the mouth, and it also has the active state of lips.

The nasal cavity acts as a buzzer in pronunciation and is separated from the oral cavity by the soft palate and uvula. Of the six vowels and twenty-one consonants in Russian, two are nasal, and the soft palate is drooping. Open the passage of the nasal cavity, and the airflow will be emitted through the nasal cavity. The remaining 19 sounds are all oral sounds, and the soft palate rises, closing the nasal passages.

There are thirty-three Russian letters, including ten vowels, twenty-one consonants and two silent letters. Russian can be heard and written, and the pronunciation of words can be seen. For example, the letter а is pronounced as /a/, the letter g is pronounced as /ja/ (in stressed syllables) or /i/ (in unstressed syllables), and ть is pronounced as /tj/, which means that the previous sound is pronounced as a light tone, that is, a semi-vowel /j/ should be added.
