I have learned some recipes now:
Roast wolf (add 30 haste level, 30 endurance, 1 hour, need 350 cooking)
Roast Wolf (40 haste, 40 endurance, 1 hour, 400 cooking required)
Grilled rays (30 haste, 40 endurance, 1 hour, 350 cooking required)
Wang Lei fillets (40 haste, 40 endurance, 1 hour, 400 cooking required)
Because you can't log in to the game now, these recipe names are all from the simplified version, which may be different from the actual traditional version, but these recipe names should be like this after the national service updates WLK. Two 350-year-old people can buy recipes of NPC in Lingfeng Fjord or Beifeng tundra, and two 400-year-old people can buy recipes of Dalaran.
