In Jiaolian Village, where a tributary of the Meijiang River meanders, the mottled slogan "Learn from Dazhai in Agriculture" still remains on the brick wall of the century-old Weilong House. On the grain drying field in the cold winter of December, 6-year-old Liu Qiangxi clutched his faded Transformers and watched his parents board the long-distance bus bound for Shenzhen. From then on, the Hakka boy's stay-at-home years slowly unfolded in the fragrance of his grandmother's tea and his grandfather's dry tobacco bag.
