It seems like you're looking for information about "triendliness" and "superexpression," as well as the concept of "trọng âm" (stress) in the Vietnamese language. However, "triendliness" and "superexpression" are not standard terms in English, so I assume there might be some typographical errors or misunderstandings.

1. **Triendliness**: If you're referring to "friendliness," it generally describes being kind, pleasant, and supportive towards others. An example might be, "Her friendliness made everyone feel welcome at the party."

2. **Superexpression**: This term does not exist in standard English usage. If you meant "super expression," it could refer to an impressive or highly articulate way of conveying thoughts or feelings. For instance, "His super expression of joy lit up the room."

3. **Trọng âm (Stress)**: In Vietnamese, "trọng âm" refers to the syllable in a word that is emphasized more than the others. For example, in the word "học sinh" (student), the stress typically falls on the first syllable: "học."

If you meant something different or would like further clarification or examples, please provide more context!
