谨 + 动词
respectfully; I (we) humbly … (in letters and speeches)
Structure
（主语） 谨 （代表…／向…） 动词（致／表示／祝／上）
What it means
谨 (jǐn, 'careful, reverent') before a verb shows the writer acts with respect: 'I (we) respectfully …'. It describes the speaker's own action.
How it is built
(我／我们／我校) + 谨 + (代表…／向…) + verb (致, 表示, 祝, 上): 我谨代表公司向全体员工致以节日的问候 (On behalf of the company I respectfully send holiday greetings to all staff). Sign-offs: 王明谨上, 谨启; also 谨此致谢.
When to use it
Letters, speeches and ceremonies. Without 谨 the sentence is plain (我代表公司…); with it, it is humble and ceremonial. One 谨 per sentence is enough, and in a chat message it sounds stiff.
Watch out
The subject is the speaker's side, never the person addressed: ✗ 请您谨致… ✓ 我谨致…. 谨慎 (careful, 3-7) shares the character but is a separate word.
Examples
值此新年来临之际，我谨代表公司向全体员工致以节日的问候。
As the New Year approaches, on behalf of the company I respectfully extend holiday greetings to all our staff.
对贵方的大力支持，谨此致谢。
For your generous support, we offer our respectful thanks.
