What other plants are there to discern directions?
Everything grows by the sun, and the sun's thermal energy forms many indirect directional characteristics in nature. Once these characteristics are mastered, the direction can be determined even on rainy days without the sun. The sun's trajectory in the sky is that it rises in the east and sets in the west, and most of the day is spent in the southern region between east and west, so the grass on the south side of the stone blocks, tree stumps and hillsides grow high and lush, and the grass on the south side of the mountain also withers and drys faster in winter; And moss, a plant that loves yin and moisture, will grow in the north; The gum flowing on the trunk is more in the south than in the north, and the clumps are large; The fruit of the fruit tree is also more abundant and sweeter in the south, and ripens earlier at the same time, such as apples, dates, persimmons, hawthorn, lychees, citrus and so on.
