Are Liu's paintings and calligraphy works collectible?

This is definitely collectible. Many of his works were exhibited in important exhibitions and won prizes. Teacher Liu's unique calligraphy style is also a clear stream in the calligraphy world. Moreover, Mr. Liu's calligraphy works are fresh and elegant, and the pen and ink are horizontal. Anyone who knows a little about calligraphy can observe it. Teacher Liu's thirty or forty years of calligraphy skills are also handy for painting. Teacher Liu focuses on meticulous painting. Fine brushwork is the most important line. If the lines of a painting are successful, it is equivalent to 90% success. Line is the root of a painting. Whether the charm is vivid or not has a lot to do with the lines. Therefore, when appreciating meticulous painting, color is not the first, but lines are the first. Eighteen strokes in Chinese painting are used in different places, and the overall charm of the picture will be very different. Just by color, it is a painting without bone strength. This can be carefully observed through Mr. Liu's paintings.
