How difficult is it for an old tree to bloom? Although it is simpler than an iron tree to bloom, it is still a rare spectacle. When Junqing's friends saw the summer that made Junqing's dying old tree bloom, they all said that it took a lot of high-intensity fertilizer to make the old tree bloom such a fresh lily. Only Junqing knew that his little flower was not a lily, but a rose, a rose with thorns.
