Tick, click, click, click, click, click, a string of crisp and rapid ringtones that seem to have their own magic, penetrating the tranquility of the morning, dancing with the slight vibration of the mobile phone, weaving into an overture about expectations. Lin Xiao, the explorer living in the urban jungle, instantly transformed into an agile cheetah. With a gorgeous turn, he ejected from the gentle edge of the bed and accurately captured the vibrating "prey" as if performing an acrobatic performance - his mobile phone, with a light touch of his fingertips, connected the end of the line connecting happiness.
