Those who know astronomy will definitely adopt it.

1.M42 visible to the naked eye, with three stars. On the left side of the belt Samsung (Betelgeuse I), there is a little flame nebula on the upper left and a little famous dark nebula, Horsehead Nebula, on the lower left. This area is a bright star cloud system. Orion also has a nebula, a little west of Betelgeuse and witch head nebula (the head should be upside down).

2. As long as the weather is clear and avoid the city glow, M3 1 is easier to see after zero, and Pegasus should be easy to find. If you find Pegasus, you find Andromeda.

Search the star map online, or go to some astronomical forums to ask for it. Baidu knows that it is not easy to solve this demand. On the one hand, it is difficult to map, on the other hand, it often leads to invalid reply address.

About M42 and Pleiades, go to Sina and ask Weibo of Beijing Planetarium. They should have calendars or something. Recently, Zhan Xiang of the Museum posted a recent big picture of Orion on the Weibo, which is helpful for beginners to understand Orion.
