Copywriting:
If the trunks of two trees rub against each other in windy weather, the bark of the trees will be worn away. When there is no wind, the two branches will grow close together and they will grow together. Two trees growing together like this are rare connected branches.
They are two branches growing independently in their own worlds, and there is no possibility of any intersection.
An accident made them meet.
They came close to each other, rubbed against each other, and finally grew together.
Life is like a long river, which may have rough waves or calm waves.
We will all come to an end one day.
