Today is 谷雨 or Grain Rain which is the last solar term of Spring. It is called Grain Rain because “雨生百谷” (Rain sprouts a hundred grains). This is the best time for sowing seed and planting seedlings. In Southern China, there is usually quite a lot of rain during this period which is suitable for growing rice and corn. In Northern China, there is a custom of eating 香椿 (Chinese toon, a kind of vegetable) on this day, whereas Southern Chinese would pick fresh spring tea and drink it on this day.
