南瓜和西瓜底部与顶部纹理相同，然而现实中的南瓜与西瓜不应该这样。。。
你们应该绘制对应的底部纹理，而非套用顶部的纹理，因为这会使得它们看起来十分奇怪（例如南瓜上下都有柄）。
Pumpkins and watermelons have the same texture at the bottom and top, but in reality, pumpkins and watermelons should not have this texture...
You should draw the corresponding bottom texture instead of applying the top texture, as this will make them look very strange (such as pumpkins with handles on both sides).
