Actions:

1. Not looking directly: Eyes represent a person's heart and thoughts. When speaking, if someone does not look directly at the other person, it may indicate guilt or that what they are saying is problematic.

2. Moving lips before speaking: Before speaking, some people may have unnatural facial movements, such as their lips twitching first, which may indicate that what they are about to say is not truthful.

3. Biting or licking lips before speaking: Biting or licking lips before speaking are subconscious actions, which may indicate that what they are about to say has issues.

Facial Features:

1. Lips not aligned: People whose upper and lower lips are not aligned or are skewed tend to speak untruthfully.

2. Protruding eyes: The saying goes that "protruding eyes have no form." People with more prominent eyes often speak in an insincere way, and their words may contain problems or hidden intentions.

3. A crooked nose: People whose nose appears slightly crooked when viewed from the front are usually difficult to deal with, and their words are hard to distinguish as true or false.

4. Sparse teeth: People with sparse teeth that let air through tend to speak carelessly just for fun, making interesting remarks that amuse everyone around them.
