He is among the more ordinary members of the La Clan, but he is still very capable compared to the average person. This "ordinariness" gives him an inferiority complex towards his younger brother Lahan. Like his father, he specializes in farming and specifically really likes potatoes.
Despite his seemingly rough exterior, he is actually a very kind person. Maomao takes pity on him because he is too nice for his own good, which makes it easy for others to take advantage of his hard working nature. It is easy for Lahan to get a rise out of him, and despite his expertise in farming, he will vehemently object to being called a farmer.
