Black Lake expressed my anxiety and compromise in reality in 2020. Although there are also many positive aspects, such as slowing people's pace of life, remember the importance of daily hygiene, and say thank you to the NHS medical staff. But perhaps it starts from in my country tens of thousands of infections and deaths have been reported, there have always been lingering anxiety over me. Since the beginning of this year, Chinese websites were filled with heartbreaking news. On the wall of my studio, I wrote done the name, age and date of death of the medical staff, and updated it daily. In March, my grandfather passed away alone in a nursing home. This makes me very sad and often feels uncertain about life and my existence. As if there is a black hole in the air, it might take me away at any time. After 2 months of lockdown, I decided to use the materials I have got at home to make a painting to reflect my feelings in the first half of 2020. And here it is, a chaotic colour on an abstract lake.
