Does anyone have the experience of teaching people who can't whistle to whistle and teach me how to whistle?

According to the method of bujuerulv 126, you can blow out the sound. Practice makes perfect. You can master it through more practice. I like whistling at work best, and it is also my favorite poem. I feel very happy. Colleagues asked me why I was so happy. I said, because I believe in Jesus, of course I am happy. I know who I trust, so I am often very happy. Tired of work, singing poetry and whistling have motivation again. The bible says, "if any of you suffers, he should pray;" If there is joy, he should sing. " (James 5: 13) when I have good faith, I never ask the Lord for my own things, but praise God, because I know that the God I believe in knows, so I praise his omniscience, omniscience and goodness. This is my trust in God. Lord, you can contain everything with powerful commands. Why should I worry about my affairs? If my father doesn't allow me, not a hair of mine will fall to the ground. Even when I am sad, I will sing to the Lord in the form of a poem. This is my favorite poem: We should thank the Lord, because you are kind and your love will last forever. When I was helpless, I called on the Lord, and he gave me enough, and he took care of me. Hallelujah, Lord of glory; Hallelujah. Praise god. For you are good, and your love endures forever. This song has a prelude, which is hummed. While humming, prepare quietly.
