2 important things need to remember when you send the token. Gas limit and Gas price.

1. Always set high Gas limit. If you do not sure how many is enough, you can set 100K - 150K.

2. There are 2 choices. Hurry: 10-15 Gwei. Have alot freetime: 3-5 Gwei.

And it seems that I have not failed to send any token with my solution.
