I watched the YY work of Xi Yangyang and Big Big Wolf, with an open ending.

Dear Warriors:
If one day you see a wolf lying in the forest with the corners of its mouth curved up to 45 degrees, then please find his smile and wake him up. Because God hopes that this love-mad and even crazy wolf can be happy. Can you help me? Then tell him, I hope your sky is always bright and as clear as water!
Then, it's been years since then!
