Tian Jiarui's acting is really really really good.. he managed to execute the scene of crying blood very well.. I could directly feel the pain even just from Reuters.. I don't know what feelings I will have and how badly I will cry when I see that scene air....

Ohh.. they said that "to shoot the blood tears effects, special liquid must be dripped into the eyes. although it looks realistic, it's painful and truly tests the actor' skills & endurance" .. and what's more amazing, tian jiarui did it in one shot 👏
