Thank you. What happened to me was, the transaction(5225cff0ac48fa59ff85553cb515e21560abbcdd0711f1179f8cd189a792d121) had been on Chain.so for 48hours while no other block explorers were showing it. However, a day later, that transaction finally went through. Any thoughts on what was happened?
Now I have another one in the same situation. No one is showing it except Chain.so

Chain.so's mempool is not reflective of every mempool in the network. This means that even if only chain.so has the transaction on their block explorer, it doesn't mean that the miners doesn't have it on their mempool.
What client did you use to send the transaction?
