The wind blew the trees along the road, shredded the shop's cloth cover, uncovered the bills on the wall, dazzled the sun, sang, yelled, roared, and echoed; suddenly slumped, like madness The elf that sprinted away hurriedly; suddenly panic, rolled around in all directions, like a demon who decided to ram around somehow; suddenly swept, attacked everything on the ground by his unpreparedness, twisted the branches, The roof tile was blown off and the electric wire was broken; however, Xiangzi was watching there; he had just come out of the wind, and the wind had failed to treat him! The text is intended to emphasize:. ['Harsh environment.', 'The plight of life.', 'Strongness of Xiangzi.', 'Hardships for a living.']
