協力して一緒にやりなさい。二人が互いに引っ張ってあげ、押してあげてやったら、倍ももっとできる。二人が行なって得たものは、二人が分けても、一人でやって得たものより多い。
Do it together in cooperation. If two people work together while pushing and pulling each other, they accomplish twice as much. Even if two people share the things they gained by working together, they gain more than that which they would have gained by working alone.
