Everything is good when new, but friend when old.
老朋友更醇香。
When did you meet with your last friends last time?
Several weeks ago.
We had talked about each other‘s recent developments in telephone, and they telephoned me.
It seems I haven‘t actively communicated with my old friends.
Remember that friendship needs interaction, otherwise you will lose these old links.
And we also need to develop some new links, which will help us broaden our social networks.
Life is like riding a bicycle. To keep your balance, you must keep moving.
生活就像骑单车，要想保持平衡，就必须不断前进。
Just like riding a bicycle, you can have a rest if you have a solid foothold.
If you don‘t have, or you are incapable of touching the ground, you must keep moving to prevent from losing your balance.
Don‘t be afraid of falling down, you can get up again and continue your journey.
