(1) Mom's implication is that if Zhang Qiang wants to travel to the West Lake with his parents, he doesn't need to see the maple appreciation activities. (2) convince mom: mom, the literary society is going to organize a group activity this time, and my plan has been made. If you don't go, you will break your promise to others. Maple appreciation is a seasonal activity. If you don't go now, the maple leaves won't look good, so I begged my mother to let me join you in this activity, and you can discuss with my father about going to the West Lake in the future.
