4. Light: Chong Lou is a shade-loving plant, likes oblique or astigmatism, avoids strong light, growth requires shading environment, strong light will wither leaves, generally seed germination and seedling stage requires better shading, and the first two years of maturity should appropriately reduce shading and increase light, which is beneficial to the accumulation of secondary metabolites and dry matter.
