According to QQ Music, Psalm 84 is a Christian hymn sung by Wu Qingguo. Lyrics: I will meditate in your residence, Lord, my heart longs for you. I want to hear your voice with my own eyes. Please bend your face. May your servant wave to me and let me rest in the arms of the Lord. You are my refuge, my strength and the crown on my head. All my enemies are discouraged, and all those who hate me are dismayed. I pour out my grievances before the Lord; Please help me out of my predicament. Turn back, O LORD, and guide me; comfort me because of your lovingkindness. I long for your dwelling place, O LORD. Please be angry with me.
