Do you believe in Buddhism and ask for a visa in Lushui Ancestral Temple? Which temple is it? Which one is better for me to cancel my visa?

You can't ask for a sign in the temple. When Sakyamuni was alive, he said that monks can't do fortune-telling business, because Buddhists say everything is luck, that is to say, it's useless to forget what your life is. Those who break the contract and change their lives will be rewarded for revealing secrets, and those who ask for a fortune will be implicated and suffer greater disasters, so the fortune-telling business in the temple is fake.
