Following the advice of Lu's father and Feng Qingxue, Wang Zhengguo placed great importance on tree cultivation. Thus, in an age where trees had been nearly entirely chopped down, the wilderness, roadsides, field edges, and spaces around the houses were all replanted with common trees like poplars, willows, elms, and also black locust trees. After several years of careful tending, the trees would provide shades of green each summer, making Wanglou Brigade once again the envy of onlookers.
When the corn seedlings had grown to the height of a lower leg, the Wanglou Brigade was filled with the sounds of cicadas.
Families without flashlights were reluctant to light kerosene lamps and would only catch a few golden cicadas that crawled up the tree trunks in the twilight. Those with flashlights were more brazen, shuttling through the cornfields and woodlands with their flashlights, spotting each cicada with precision.
