Chingling will only evolve into Chimeco if it's happiness is full at night time.
It must be leveled at day, 10:00 AM to 5:59 PM with high happiness. It will not evolve at morning, and if it levels at night with high happiness it will evolve into umbreon, never to become Espeon.
Let your Pokémon hold Soothe Bell and train OR feed it Berries that lower its stats but makes it friendly- DON'T overdo it.
Make sure your umbreon has alot of happiness and lvls up in the night time ( 8.00PM-4.00AM). Give it a soothe bell to increase its happiness and you can also give it calcium, iron,etc. Don't let your eevee faint, make sure your eevee does not get poisoned, paralized or sleep.
